Any click creates another unwanted timezone until my task bar is full. The docs do not describe where the config is to manually edit. Thanks for creating the extension.

The extension is incompatible with the current GNOME version

I would like this to show me Los Angeles, Phoenix, Denver, Chicago, and New York. In that order. However it seems to be in alphabetical order. So perhaps just keep the times in the order the user provided? So if I select the aforementioned cities in that order, they should show up in that order?

I would also like it, as it was mentioned in #10 , to simply have UTC offsets as well.

I'm using ubuntu 19.10 and gnome 3.34.2 and I can add new timezones, but the if i try to remove them, it adds a random new one, and when I have more than four timezones, I'm able to remove the ones on top, it's kind of weird bug.
So, from the screenshot, there are 5 options in my list of active clocks, the one on top, when I put the cursor on top of it, the background is grey as you can see, but if I move the cursor to the option below, the background of that option is not grayed, so if I click the first one, it gets removed, but if I click the second one to remove it, instead of removing it, it adds another random clock to the active clocks. My guess is the acts like the active clock are transparent and clicks some list hidden behind or something strange.

metadata.json would need to be updated to support gnome 42

Thanks

Example: if you want to add San Francisco - USA, you are out of luck.

I guess that having all the biggest cities in the world with the current UI would be super messy if not impossible, but what about having at least all the time zones (just by UTC offset, or the list will be longer)?

Then if you can pick the time zone you want, it would be nice to have the possibility to edit it with your own city-label, so the extension could cover all the places in the world with just the time offsets and an editable field.
