What are you trying to accomplish?

Remove the project selector from top menu left, and move it to side bar menu.

Merge checklist

• [ ] Added/updated tests

• [ ] In the AC it is written, that the drop down should have some spacing to the left side. Currently, it is glued to the left side
• [ ] For me it looks like there is a margin missing around the project selector. It looks somehow squashed compared to how much space for example the submenu headers have. In figma, it also looks as if there was some margin around it. Maybe you have to double check with @marcalcobe

I talked with Marc about the spacing on the left side of the drop modal, the decision is to ignore it now.

One other thing that just came to my mind: I guess, the project selector should be sticky and not scroll with the other elements when the menu is rather long
