In the recruitment menu with mouse, you have to click on the unit then the recruit button, which is a bit clunky IMO. I would prefer to be able to simply double click or at least have a more convenient keybind than Enter. I'm also one of the weird PC players who currently prefers a controller (for Wargroove specifically) for this and a couple other reasons, but this, along with the ability to rebind keys, would help to close the gap since my preference is by a fairly small margin.
