Copy/Paste Allowance in Script Box

I suggest allowing us to paste more than 1,100 characters, but with anything over 1,100 being in red, and in real time and changing as we condense, reword, revise, summarize, etc. The reason being is: it would be nice to have all my thoughts in one place so I can see the script while I whittle it down to 1,100 or less ! Thank you!
