Comp Duration Script
Quickly edit the timeline duration
This dockable After Effects panel lets you quickly increase or decrease your timeline duration without needing to open the Composition Settings window.
I originally developed this for my workflow, to quickly +/- 1 second.
However, I noticed that other animation software can quickly alter the frame range on the fly without opening new windows.
So I expanded on the script and have made it available to everyone—for free!
