User reviews
Thank you for all your work, it looks and works great. I do, however, second the review about dark mode. If there could be some kind of option toggle to set/disable a different weekend color, that would be great, please. For now, I just unchecked the "Show weekends" option in the Google Calendar settings. I'll submit the feature request on GitHub.

Please remove the background color on the weekend days. It makes dark mode unusable.

best event merge extension for sure, but is there any way to not have the blue background behind the weekends. its really ugly to me, and clashes heavily with my event colours. especially when i already have an extension that shades days, but its hidden underneath this extensions weekend colour.
