Right now, Studio 2 allows me to use other Topaz plugins as non-destructive layers. A competing program, Luminar 4 allows plugins by Topaz and other manufacturers to be used in a similar way, in layers. This would make Luminar a better hub, but, in the move to Luminar AI it would appear that layers are being dumped with access to Topaz and other plug ins going, as well. No other Photo editor application has this ability (although pixel editing programs like Photoshop do.) Access to third party plugins in layers would make Studio 2 even more compelling as a hub, and would allow Topaz to access abilities being abandoned by Luminar. Thanks!
