This is (hopefully) a quality of life update, that many have been waiting for.
The project has long since outgrown my own need and thus people were running into scaling issues, that I didn't experience or originally consider. The Clockify API is rate limiting after just a few calls, which will cause unpredictable failures, such as having buttons not update anymore, if you add too many on one screen.
If your whole page is filled with buttons, it can still be a bit of a struggle to have the buttons be responsive, but the plugin should be able to work with more than three buttons on one page now. 🥳
