need ability to disable T/A on a per text box basis
There are certain text boxes where having T/A make suggestions is of detriment such as address bars of web browsers however disabling T/A completely prevents use in emails/text boxes etc...
TypingAid checks to see if it should be enabled/disabled based on switching windows. To do this, it would need to know when it switched controls, not just windows. Maybe the event EVENT_OBJECT_FOCUS could be used for this.
Then, I'd either have to hardcode the controls to ignore for each process (unlikely - maybe I'd only do it for a limited set), or somehow allow the user to define them (not very friendly... unless I made a window spy like program within TypingAid).
@Skrell - if you really need it I would write a small helper script if I where you which would use a timer to check the program and control - if it matches a control where you want to disable TA simply send the suspend command http://ahkscript.org/docs/FAQ.htm#close
