I worked around the UI issues brought by Adobe’s new script engine/library in CC 2015. Adobe also stopped Extension Manager app. So I updated the installation tutorial for CC 2015. It needs to use ExManCmd tool in terminal console.
Kwik3.5.2 did not work with PS CC2015
TreeView and Listbox with multi columns are changed a little bit about the appearance and the event handling. Because Double Click does not work for them, please use a new Select icon before you remove an item or move up/down items in tables.
Here are the screen shot of the commands that are affected with Adobe CC 2015.
