I recently started working with the Grease Pencil and can't seem to figure out how to tweak and edit the keyframes of Grease Pencil. I want to be able to move them around on the timeline, but I'm not sure where to do this.
Normal action-based animations have the action editor where I can move the keyframes around. The grease pencil doesn't appear to have anything like this. Additionally, when you delete all of the strokes on keyframes, the markers don't disappear on the timeline. This is going to get messy fast if I can't fix this.
I'd rather not have to delete entire layers just to remove markers on one frame of the timeline.
To be concise:
How do I remove these?
