Older version of app

This is a very long shot but worth it.

I'm looking for the Pro version of the app Pie Control by Coolace, version 4.3. It HAS to be this version. I have no problems buying the latest pro version of the app however this older version has a feature much appreciated by me that the developer removed after lollipop due to incompatibility. This incompability can be easily solved by a xposed module. If anyone can help me I'll be forever grateful. Thanks!
