I brought this up before but there needs to be a way to have an icon selector as on large monitors you can have multiple titlebar icons. I currently have 17.
As these button are mainly doing similar functions there would be a way to folderize them so they do not take up so much space...

for example:

top left
top right
bottom left
bottom right

Rather than have an icon for each one, a containing folder icon and then a submenu to select the correct icon within the titlebar folder...

On small windows you cannot choose the drag bar.

Any solutions?
