A simple extension to modify the length (exposure) of greasepencil frames.
With the mouse over the Grease Pencil Dopesheet, press:
D
to shorten the current frame by 1 frameF
to extend it by 1 frameHold down the key for less subtle adjustments.
The shortcuts change the length of the displayed frame(s) for every unlocked layers in all selected GP objects. Make sure you isolate the layer you want to affect or lock the ones you want to keep in place.
When the current keyframe in any unlocked layer (even if hidden) is only one frame away from the next, shortening frames is disabled to avoid overwriting frames by accident.
You can remap the shortcuts to any other key by going to Preferences
> Keymap
and searching for "nudge".

This extension does not require special permissions.
This is one of those simple yet invaluable addons that you really can't live without. With a few key pressed you retime your Grease Pencil animations with speed and ease. Once you try it, you can't live without it. Thanks so so much!
