I just posted build 1133 with these changes:
- Fixed RTL folder names having wrong text alignment
- Fixed "account switcher panel" becoming "disabled"
- Slightly darker color of account names and folders (previous build made them too faded)
Nothing new with per-account colors yet, however...
Lacho (the designer) really is thinking about it, we discussed it today.
At the same time, as he already wrote above, we're going to release a beta version with "bars" to collect feedback / ideas from a larger number of users.
It is understood that these colors have a practical purpose not just visual.
