make columns more distinct

[hogi]

☐  cool new feature
☑ could help many users!

☐ removes a „bug“

☐ nice to have

☐ nobody needs it

sometimes it's hard to find the right column again and again.

some suggestions to make it easier:

- define special colors for special columns (or groups):

- make the vertical line between groups thicker
