Unable to move saved windows between PCs

I save a window (not a session) from TM in JSON format. I then take that JSON file to a different PC (running same version (current a/o 7 Sep 25) of Brave). In TM on the target PC I have the TM Active Session tab open. I click the "Import from file" icon, choose the saved JSON file, and get told, "Failed to Import Windows." I then go to the "Saved Sessions" tab and do the import again. This time I get a message, "File imported." But I don't see the imported window and its tabs anywhere...not in Saved Sessions or in Active Sessions.

1. What am I doing wrong?

2. Is there an easier/better way to copy the tab config from one PC to another?

TIA.

Tab Groups will not expand

Hi there,
I’ve been using Tabmanager.io for several years and recently noticed a regression in the session viewer interface. In older saved sessions (e.g., from April 2025), the arrow next to each tab group expands properly to show the tabs inside. However, in newer sessions (e.g., saved today, September 2nd), clicking the arrow does nothing—tab groups won’t expand, and no tabs are shown.

This issue persists across multiple saved sessions and browser restarts. Saving still works fine, so permissions aren’t the problem. It appears to be a UI or rendering bug introduced sometime after April.

Steps to reproduce:
1. Save a session with multiple tab groups.
2. Open the session viewer.
3. Click the arrow next to any tab group.
4. Observe that nothing expands—no tabs are shown.

Older sessions still expand correctly, so the issue seems tied to newer session formatting or a recent extension update.

Would appreciate any insight or fix you can offer. Thanks for building a great tool—this feature is essential for managing large multi-window workflows.

Best,
David

Windows Names

I have several windows open and I have named them. Why wont the app save my named windows instead of assigning random windows "numbers" to them. Seems like a basic function to me.

Saving URLs in text format (for a single window)

Greetings,

I see from the hamburger menu for a window that I can 'export as JSON' and 'export as CSV' - but is there a way to save the list of all URLs (tabs) for a window to the clipboard?

My use case is to quickly share a related collection of URLs I've put together in a window, for someone to either open with Tabmanager or click-open each one.

Cannot drag between groups when a search filter is active

Steps to Reproduce:

1. Search for a term that finds multiple tabs in more than one group within the same window
2. Expand the tabs
3. Drag a tab from one group to another

It seems to move it to the target group, and then move it back again.

Workaround for naming windows

I currently have a 18 windows (it's not an addiction, it's a superpower 😁) and I needed a way to quickly rename all the windows in TabManager so I wrote a script to do it.

This renames each of your windows with the title of the first tab. I put it in a bookmarklet so it's easy to run.

// Works with v2.0.1 of Tabmanager.io
for(const win of document.querySelectorAll(`[aria-label="browser window"]`)) {
const name = win.querySelector(`[aria-labelledby="win-${win.id}-label"]`).firstChild.innerText;
win.querySelector(`[aria-label="Name window"] button`).click();
document.getElementById('window-title').value = name;
document.querySelectorAll('.MuiDialogActions-root .MuiButtonBase-root')[1].click();
}

If you want a nice first tab for each window you could use this example:
(Segoe UI is a Windows font so you might want to change that if you're on another system.)

data:text/html;charset=utf-8,<style>head{background:%23ccc;display:block;width:100%;height: 100%;text-align: center;}title{display:inline-block;top:50%;font-family:"Segoe UI","Segoe UI Emoji";font-size:15vh;position:absolute;width:100%;left:0px;margin-top:-15vh;}</style><link rel="icon shortcut" href="data:image/svg+xml,<svg viewBox='0 0 64 64' xmlns='http://www.w3.org/2000/svg' style='height: 64px;width: 64px;'><text x='0' y='52' style='font-size: 42pt'>👨</text></svg>"><title>👨💬📧📑</title>

Nothing in expanded group that was unexpanded when Tabmanager was opened

Tab manager doesn't seem to know what is in unexpanded groups. Could it somehow re-load the tab data when it expands a group?

A few suggestions

I've given this extension a 5 star ⭐⭐⭐⭐⭐ review as it is the best extension for organising tab groups. I do have a few suggestions that would make it even better:

1) Add a screenshot showing tab groups to the chrome web store landing page. It wasn't immediately obvious it could manage groups. (A more zoomed in screenshot as the first screenshot would probably help too.)

2) Allow selecting across more than 1 window.
2.1) Ctrl + Click in tab in 2nd window when tabs already selected in another doesn't clear existing selection
2.2) Top level "Move selection to existing group" button with menu to select group that has search/filter feature for finding the group.
2.3) Top level "Move selection to existing Window" button with menu to select window that has search/filter feature for finding the group.
2.4) Add "select all search results" button.
2.5) Changing search doesn't unselect tabs (even if they are now hidden).
2.6) Add a "only show selected tabs" filter.
2.7) Add a "only show windows with tabs" filter. (Which would show unselected tabs in those windows)

NB: these features would allow building up a selection across multiple windows using the search feature, and then manually selecting more tabs before moving them all at once to an existing group/window.

3) Can groups have a count of the number of tabs in them the same way that window do?

4) Add a button/menu option to each "window" for "Collapse/Expand all groups in current window"

5) Add a button to search results for "Collapse/Expand all matching groups" next to "Close matching tabs"

6) Add a button to search results for "Suspend matching tabs" next to "Close matching tabs"

7) Can you make it aware of virtual desktops? I have some windows open on other desktops, so being able to hide those would be very helpful.

8) Could there be an option to hide all the "close tabs" buttons and menu options. I'm slightly worried that one day I will click on one by accident and close a bunch of tabs. (Do they prompt you to confirm?)

9) Name windows after the Title of the first tab.
(You could also post a comment on the following chromium issue requesting a window name API with a link back to your extension: https://bugs.chromium.org/p/chromium/issues/detail?id=1190160 )

10) Could there be a way to exclude some tabs from suspension?

Keyboard Shortcuts / Quicker Way to Restore a Saved Session

Loving this extension and use it to keep separate windows depending on what I'm working on. Right now it's a few clicks to open the manager and then go to saved sessions and click 'restore' next to the saved window I want - would be amazing if there was a quicker way (like custom keyboard shortcuts to achieve this)
