One wish list item I'd offer a bounty for (if it's within my modest means!) would be getting QB64 to read separate input from multiple USB mice plugged into the computer.
Preferably this would be cross-platform (I did research a while back and it looked like it was possible for PC, Linux and Mac using different methods, not sure about DOS) but at least for Windows.
Microsoft's RawInput API can do it, and I found a ton of examples, but alas this is just beyond my capabilities and/or free time :-( so to anyone who can get it done, what's it worth to ya? LoL
Here are the discussions about it with links to research findings / related libraries / sample code / etc.:
