Suggestion to isolate the cursor within an input

[cinam0n]

If an input window was opened via the menu, the cursor should be isolated within the input and not allow re-clicking within the still-open menu.

It would also be good to have a function for closing an input, similar to MenuData.CloseAll.

@outsider31000 Would something like that be okay with you?
Then I'd sit down and work on the suggestion along with my other reported issues and prepare a PR.
