As a developer, I always have several windows opened. In most of situations, I just want to switch between two windows, back and forth for many times. I do hope 'Ctrl+Tab' behavior should always go back to the exact previous window. But currently in PL/SQL Developer (version 10), it just circle around several window, i.e., the window order does not adjust according to their usage.

I hope this behavior can change in the future release. Or, is there any workaround?

If someone really want to go to previous previous previous ... window, he can press 'Ctrl+Tab' several times without release the Ctrl key.

Use
Cntr+Tab (back)
Cntr+Shift+Tab (forth)

It's painful to always remember what key you pressed last time, especially when you worked for a while in one window and suddenly want to go back to previous one.
