The button shaped cube should be a button.

**Is your feature request related to a problem? Please describe.**
When I tried to click on the round green cube, it did nothing. It took a second to realize that I need to click the title.

**Describe the solution you'd like**
You could make it a button.

**Describe alternatives you've considered**
If you don't want two buttons that do the same thing, just shift the rounded cubes color to light gray. Or you make it a tag like you do with the language. You could additionally clarify where to click by underlining the title.

**Additional context**
See the round green rectangle? You can't click that. Minor issue, but a bit annoying.
