I been use free trial with this app from web, and I can't really tell difference between "Lifetime Version" and "Standard Version", then I found out one day I can purchase it on App Store, so I bought it, it was good, or it might always been that way, when I tryed open app with MultiPanel, it always open the app on the left or top if it is on the left or right side, a lot bugs... I am looking forward to see an update soon Thanks. One suggestions, pleease add Active Dock to App Store if you can.
