Move focus to next window (same app)

Mac only allows one shortcut for 'move focus to next window' which sucks as the back tick ` key is not placed the same place across input language. For anyone who switches input language regularly this is a major pita.

Could you include a 'move focus to next window' functionality please?

Could you mimic this by having your desired trigger enter the keystroke for switch to next window?

That is what I have done, but it is not perfect as some applications have their own shortcuts that overrule such as chrome and iterm2.
