Command Tab for Easy Command Use

If you're the operator, if you do something like Caps-Lock, then while its on, there'd be a command screen with simple commands like Fill and Summon. With Fill, it would show an intractable 10 chunk radius map with block names and a ruler. You can edit the world with undo and redo, but when you press enter, the command will execute. If you do the summon tab, it will show a bunch of entities you can summon, with a search bar, if you click one, it will summon WITHOUT closing the tab, allowing more than one summons. If you just add more commands into this list, such as give and execute(will bring back to tabs but with an added choice of executing to a different entity, maybe with the summon search bar), and some ideas might be in the comments, if people are willing to comment on this post. Sincerely, Bats.
