Ipad apps just do basic editing. What is good is they let you do the edits much quicker and save wear on your keyboard. I should use them more. But that doesn't solve the problem of holding the edits you make. As i wrote to Diki I went thru all 82 Styles I use and saved the edits, turned on Preformance hold parameters and its seems some still revert to the old settings.
