Our customer is moving to PDFTron from AutoVue do the number of problems encountered using AV desktop deployment for renditions.

During testing, they noticed that (unlike AV), PDFTron does not have the "undo/re-do" arrows.

I can see on the link below that this may be possible using the cross platform API?
