In previous versions the touch features worked much better. I can no longer do a long click for a right click in the Development panel, nor can I drag images into collections. In the Development panel, I cannot use my arrow keys to adjust sliders. The specialized touch gui seems as if it were released without ever being tested for usability. Is there an update which fixes these problems so that the 2015 versions are as usable as previous versions of Lightroom? When will the next version of Lightroom be released which will have practical usability updates?
