The extension isn't working in a platform

Hi Jorge,

I am trying to run the checker inside platforms and it does not work (anything that requires a login, such as outlook). Would you know why? does it only work on open webpages?

Awesome tool btw! thanks for that.
Regards,
Ana

The extension isn't working in a specific page

Don't know why, but just in one page the extension isn't working. Is there a chance to force the extension to work? thanks!

Great tool but could do with an extra feature to help support devs tracking down the issues

Be great if it gave you the element id/class or selector to help track down the offending css/html/js. Even if it just console.log'd the target item, then the dev can take it form there in devtools to backtrack. Some elements which say not visible are near impossible to track. I have a few which weirdly say white background and text, but have no way of identifying what it's picking up with this issue. But similar issue with others, I've had to search for hex (and also convert to rgb) to track down from code, when I feel it could have been possible to do this from this tool with a bit more work.

Just want to reiterate I really like your tool for seeing contrast issues, just a little more help in working out what has the issue and it's be even better :-)

Change panel position

Hi. I like your tool, but i struggle to find the setting where you change the position of the panel. It covers the whole menu and the most detailed part of our application.

I saw in a comment below that you said "The only option to change the panel position now is to place it in the right of the window instead of the left. If that helps, you can access to it in the configuration panel."

Where is this setting? I've checked the extension settings and the panel settings.
