Yeah, 0.1 is pretty awful, but the paid version is currently on 0.41 and it's practically magical in terms of performance and speed, and includes a good chunk of the stuff you've listed.
Definitely has the lowest VRAM usage out of all the AI GUIs too I think, especially since they added the low VRAM usage toggle. I'm pretty sure some people are rendering with 3GB VRAM and making pretty solid images at a decent speed, too.
I'd really like to know when/if GRisk ever plans to update the free version, or if it's just doomed to stay as some janky unfinished load of WIP to serve as a "demo" for the paid version.
