I would like to see either an updated sendkeys function that sends the keys as they are actually typed in the script, not being effected by Capslock or Numlock, or as another suggestion, maybe a function like keystate(), which allows you to not only set the state of capslock and numlock, but also allow you to check it.

I'm aware the AutoIT has this functionality to some degree and I would consider this suggestion pretty low priority. However, it's something I have run across, and have seen other people asking about as well:
Check for CAPSLOCK
What is NumLock key status?

I have absolutely no idea how hard this would be to add, but I've found a few articles discussing how this is done in vb:

HOWTO Find Keystate of Numlock, Capslock etc., in VB
HOWTO: Toggle the NUM LOCK, CAPS LOCK, and SCROLL LOCK Keys
