If I press Control+Tab it show editor list, If I have two tabs, I must press twice Tab to move to neighbouring tab.
If you're suggesting that the editor list be skipped and it just do a straight cycle, I agree.
Or at least make it an option. Or if it already is, point me to it, because I couldn't find it.
Use the keybinder plugin to change (or remove) the keyboard-shortcut for "View -> Switch tabs" in "Settings -> Keyboard shortcuts".
If you are on windows and use the 10.05-release with the installer it might be not installed.
In this case just rerun the installer and make sure you mark the keybinder-plugin for installation.
