Describe the bug (actual behavior)

after improvement #398 the menu with clusters started to look bad:

• there is a huge margin between clusters. with a large number of clusters it looks very ugly, uncompact and just takes up twice as much vertical space
• cluster names are displayed in gray color and without bold selection (and it makes no sense, as the selected cluster does not differ in style).

on the screenshots above you can see it very well
