Using v2.0.6.1, I have turned off "Tab order controlled by recent use". However, pressing Control+Tab goes in reverse order through the tabs (right to left). And pressing Control+Shift+Tab goes in forward order (left to right).
Expected: Control+Tab should go forward/right, adding Shift should go backward/left.
I don't know if this still happens in the beta, I will try to install later and check. Just wanted to know if this was a known issue.
