As many of the applications (and maybe best practices suggest) are using lighter colors to highlight active tabs, it becomes confusing for Spark users to determine which tab is active (especially when there are only two tabs in window). So here are some suggestions to change this.
- Reverse current highliting, so blue background would be for inactive tabs and whole tabbar (like they are in shadow)
- Emphasize active tab by bolding the nickname. This will make chat window tabs work like Contacts/Conferences tabs in Roster window (consistent design). Roster tabs highliting should be reversed too. As tabs with new messages are marked with bold+red text this shouldnt be hard to distinguish. Unless for colorblinds.
- Make active tab a part of the chat. This means hiding bottom border of the tab.
- Make sure text in inactive idle tab is still readable enough.
