Modify Journal to accepting eraser input from a Penabled pen with the eraser feature. This would be beneficial by simplifying and accelerating the cutting or deleting actions. No need to pick an erase mode or function, just let the pen directly designate objects to either cut or delete. Direct eraser support could also assist in maintenance of annotations in documents.

(Yes, selfish, whiny user that I am. I am a programmer and do understand this seemingly minor behavior probably impacts the Journal code quite a bit. )
