I'd like to propose an option so that tab switching via ctrl+tab works like it does in Visual Studio - selecting the previously active tab. I think being able to switch back and forth between two tabs is more useful than just iterating through the tabs (e.g. having 7 tabs, switching between tabs 2 and 5 and back and forth).
If there already is an option for this or was discussed elsewhere, I couldn't find it, sorry.
On a side note, playing with the shortcut keys in the options panel, I found that disabling "Select next tab" or re-mapping Ctrl+Tab to something else (e.g. "Select last tab") did not change the behavior of ctrl+tab, it still selected the next tab.
