The following might or might not get you where you want...
If you're looking to manage (hide) windows, then ⌥⌘H hides all windows other than the current one.
The ⌘H chord hides the current window.
To see the available windows, four fingers up (on a touchpad enabled for this gesture) displays all windows. Four fingers down shows all windows associated with the current application. The "hot corners" feature can also be used for a core set of display functions.
You can also bind the Mission Control and Application Windows functions to keys; by default, F9 and F10 are used, if enabled. See the Keyboard Shortcuts in the Keyboard settings in System Preferences for what's available on the particular OS X version you're using.
You've already mentioned ⌘⇥ command tab, which triggers the application switcher.
FWIW, this isn't the best spot for suggestions; Apple may or may not see stuff offered here. It's usually best logged via a bug report (as an enhancement request), if you have access to that.
