Frequency separation plug-in, updated

Hi all. I’ve updated my frequency separation plug-in for GIMP to work with GIMP 3.x. As you may know, the API for creating plug-ins has changed for GIMP 3, so I took the opportunity to rewrite the old plug-in. Please give it a try and let me know what you think! https://www.chuckhenrich.com/gimp-…
