I have been using PDF-Exchange for some time now as an replacement for Adobe and have purchased a few licenses to support the work. However, for productive use PDF-Exchange lacks improved touch / pen support.
- removal of automatic object grouping in drawings ... this would prevent (unintentional) moving of individual drawn lines.
- manual grouping of objects (lines, drawings, images, ...)
- a simpler menu for changing the pen properties in "touch mode" ... possibly optional insertion of a small menu bar ... see Samsung and Apple
- Microsoft Surface Pen (and other pens): Assignment settings for pen buttons ... e.g. selection key for selecting objects ("Free Form Selection") ... Currently, this button triggers the context menu ... but this functionality can already be invoked via finger touch.
- improvement of the eraser ... please make it easier to resize the eraser and switch between 'complete line eraser' and 'area eraser'
Many thanks and best regards!
