Please have a confirmation of some sorts before buying MTX

Currently you press X to look at an MTX and press X again to instantly buy it. I'm often a bit jittery and prone to double tapping a button when I only wanted to press it once. This makes looking at the details of an MTX a stressful experience and I recently accidentally bought something that way before the details finished loading. I didn't mind it too much so I didn't try to get a refund but it would be nice if this would be changed. Either split the functions across two buttons or introduce a little popup before finalizing the buy but that would also need to not just be the same button so might as well go with the first option.
