Until Adobe possibly offer such a thing, a script can be used to create a larger prompt:

1. Copy the code text to the clipboard
2. Open a new blank file in a plain-text editor (not in a word processor)
3. Paste the code in
4. Save as a plain text format file – .txt
5. Rename the saved file extension from .txt to .jsx
6. Install or browse to the .jsx file to run (see below):

Hey @rickburress, 

Thank you for sharing your idea! Can you share a few specifics? Such as how much larger, and would this be docked or the free-floating Contextual Task Bar? Specific will help us create an actionable request for the team.
