Ctrl+alt+P should show all projects, INCLUDE currently opened projects

I guess the ctrl+alt+P (project switching) should work the same as the ctrl+P (file switching) tool. In the file switching tool, no matter the file is currently opened or not, it shows up in the list. And I can do both "open file" and "switch focus" using the same hotkey ctrl+P

I know I can use alt+tab (on windows) to switch between opened windows. but using the same hotkey (ctrl+alt+P) for both open project and switch project focus can be very convenient.
