In Studio 1 you could save modifications of your Adjustment Filter for later use as a Preset. This was a big timesaver. In Studio 2 there is only the work around with SAVE LOOK. The drawback is:
There can be only the Adjustment Filter layer
You have to copy or move your saved look from C:\Users"Your name"\AppData\Local\Topaz Labs\Topaz Studio 2\Looks
C:\Users"Your name"\AppData\Local\Topaz Labs\Topaz Studio 2\Filters
f.e. you created in GLOW a new effect and saved it as MyGlow#1. In the Looks directory
you copy or move MyGlow#1.tpr to the subdirectory NGlow of Filters
To use the new preset you have to restart Topaz Studio.
This Workflow is inconvenient and insufficient. TopazLabs should implement a SAVE PRESET Button as they did in Studio 1
