Navigation overhaul
Current navigational sidebar is obnoxious and only gonna get worse. Collapsing it is a band-aid solution and won't work in the long term (more icons for everything = confusing)
Proposed solution (pay no attention to lack of post form):
- Timelines switcher that switches right column between different timelines
- Good idea would be to make entire right column a separate component that contains any timeline selected, this would set some ground work for multi-column support, if we ever decide to implement that
- Non-timeline pages go into user (or burger) menu + logout/administration links
- Next to timeline switcher there should be a "back" button (including on non-tl page and on user page)
- There also should be quick-switch icons to be able to get to home tl, dms, interactions, TWKN and local TL.
There are still some question regarding how user/burger menu will work and how to do some onboarding so that existing users don't get confused by moving stuff into different places
