I use it to test expressions that search OCR text for multiple-date formats and invoice information. Sometimes I have long expressions and large target strings. When this happens, I would really like to be able to turn off the real time testing because my machine takes a while to process each keystroke - it would be cool to turn this feature off or only search when the text has not changed for >0.7 seconds (configurable?) or maybe on a key-combination.

I would also like Regex Coach to fix all my OCR errors, make my tea and remind me about my wife's birthday.. ;-)
