Comments on the functionality (not the implementation): 1) I'm really excited to have this functionality in Okular (My work on the undo functionality was also primarily motivated by the desire to replace Xournal with Okular for tablet PC ink document annotation). 2) How difficult would it be to add something like an "erase ink strokes" option to the tools.xml. Xournal has this option and it controls whether an ink stroke is fully deleted by the eraser (as you do for the other annotation types) or erased incrementally (your current implementation for ink annotations). I've found both of these settings to be quite helpful under different circumstances. - Jon Mease On March 21, 2013, 1:26 a.m., Peter Grasch wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
