Yeah, I had the same thought until I started using wireless charging more often. At home, I prefer an angled charger, where I can partially see the phone. At work, I don't mind the flat charger.
Now, another suggestion I have is creating a "make shift" wireless charging stand. It could easily be accomplished using one of those flat wireless charging stands and a cheap stand. All that would be needed is a stand that has a thick enough base to hold the phone propped up, with the wireless charger glued to the stand (needs to be strategically placed, in order to work right).
I've been thinking of doing a DIY, just to create my own "stands."
