I believe in you software pros and with out a doubt, if you were in my line of work, you would be frustrated with the editing and mark ups too. The original editing functions were the best hands down. Now I’m always up for improvements but in the right direction. In a short description I can give this as a starting path. Take some blue prints, drawing, or even a photo. Now I need to make changes,comment, show adjustments, clarify my work, have my notations presented neatly, and most of all ( erase my mistakes,lines,arrows,comment boxes,writing,drawings,highlights) to satisfy the next set of eyes who look upon the finished product. After 6 months of using this platform with a team of 15 tablet users sharing construction drawings, blue prints, and documents; I just wish we could roll back the clock to the old days before the update happened and keep the same editing options we once had. Change is good, but consistency is key.
