So first, thanks to Francois for redirecting me here ..
Have just installed a trial version and 'played' with it briefly.
First impressions are good, not sure on what the native editing space is, though.
Ps plug-in support:
Topaz Detail, Clarity, InFocus work, Remask doesn't.
Imagenomic Portraiture works, DxO Viewpoint2, Focus Magic don't.
For portraitists: good native implementation of Frequency Separation and Liquify.
There's a lot under the hood - so yes it's a'steal' at €39 and though not a full Ps replacement yet, it covers a lot of ground, some of it better implemented as well. The plug-in compatibility needs research 'cos they've got both 'native' and 'global' support - the differences and usage of which at this stage beats me, but it's a step in the right direction.
