very nice!
i would like to use this mod with the other and i do not have to change anything. thank you very much.
BUT! to follow your request to comment further, i am not sure how it behaves and works with the already working awesome TAB command.
i think the function is built in the GAZ UI MOD:
when selecting different domains, you can shift through them with the TAB.
cool is, even if you give them a command, you can switch back to your previous selection.
so this MOD will break/override this nice TAB function.
but (again, which negates my first but!

and your tool is even more handy because most of the time only land is the one we want. it prevents even more clicks to deselect air units or others.
very good work and thanks again!
