Looks really nice @tomek2k1! I like the subduing of the color of tags as well, less noise.

What looks like it’s in the code but doesn’t show in the screenshot is a search field on top in case of many tags, just like we do for the People menu. Is it just an outdated screenshot?

I don't think we should remove color altogether. We can just make it a low-opacity background color instead of an outline.

The screenshot was outdated. A search field is also included.

The screenshot was outdated. The colors are unchanged.
