Draggable and inline titlebar for MacOS electron app

Let me know if the Edit icon on headerbar should be removed. The initial idea was to let MacOS users have a button that does the same thing as clicking the entire top area on other systems (open modal menu).

How it looks:

Works great!

The way it is right now in the main repo is a bit confusing since mouse hover on each of the option opens the same window anyway. I wouldn't add another redundant trigger that further confuses users. (Even the way it is now should be reworked imo but that's another issue)

I felt this too. And I suppose yeah, the edit icon doesn't add much to the design. If the headerbar isn't clickable, hovering on the individual items should already hint the user that they are clickable
