Strikethrough is not working

Until recently, this extension was working perfectly. Sometime in the last few days the checkbox that allows one to apply the strikethrough style to an event has disappeared. I've tried uninstalling and reinstalling the extension, disabling then reenabling the strikethrough option - just can't get it to come back again. :(

Customize checkmark?

Would it be possible to add our own custom checkmark instead of the green box? Other than that, this is a PERFECT add on to Google Calendar, makes it much easier to keep track of things. Thank you!

Issue with Strikethrough in Koreans Titles.

Hello, I've found an app that seems very useful to me, but unfortunately, it doesn't function properly in a Korean languages. While strikethrough appears well in event titles written in English, it doesn't show up in Korean. Do you have any update plans for this?

Add Our Own

Is there any way to add our own marks? I would love to be able to make some for each type of event. Job completed, invoice turned in, haven't seen anything...etc. Thank you.

This is a great extension. Hope you can get it to work. I don't get either Check mark or the "X" mark. I have all the options checked.

Now an essential feature of my calendar - is there any possibility of using it on Android as well?

I now check off all of my calendar events in order to manage blocks of time effectively. At present, this only works when in front of my laptop, but it would be amazing if it were possible to check off events on the fly from Android as well. Is this something that is possible & what would it look like? Many thanks for your great extension!
