sidebar tweaks

[ootada]

few observations on 3.3.0 sidebar:

• session titles seem to be off by 1 pixel vertically
• tab title text wraps after pinned tab icon (should not)
• active sessions should be differentiated visually (eg, by making background slightly darker and text slightly more black or so)
• 'set aside' / 'restore' text could possibly be replaced with 'minimize' / 'maximize' icons (saves space, correlates with the new session behavior)

Thanks for reporting this, the unintentional tab title wrapping was in easy fix (will be shipped with next release).

Regarding the session title offset, I might have a look into it but it is not a priority to me. If anyone else is interested in fixing this have a look at this file. Happy to accept PRs for this.
