My configuration is not complete customizeable. You can select a tool for the eraser, a tool for right and middle click and a tool for your touch screen. This is easy to configure and understand, and usually you don't have more devices. (Else if there are new input devices or I didn't think about a common case we may add an additional configuration....) Implementation details: For the touchscreen you have also to select the device, because I don't know which device is the touchscreen. You can also disable your touchscreen for drawing, so if you touch the screen first with your hand and later with the pen there is no change in the document. And if you start drawing (don't matter with which device) all other devices are disabled for drawing. So if you are drawing and your touchscreen generates also input this is not handled (I don't have a touchscreen, but a friend of my had such problems with the current Xournal, so I added all this cases...). Ah yes, and if somebody move your mouse while you are drawing nothing happens also, I have often connect a mouse to my tablet, and we don't have so much space in the lecture hall;-) Andreas > Denis > > ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
