I'm real interested to hear what other people think of the Crucible RPG for and from FoundryVTT. Since I'm not a Patreon member, I missed out on the early bits, but from the screenshots I couldn't discern if it was a D&D 5e clone or something unique.
Plugin support stopped me as well. I like the direction taht Helix is going, but I think it's got a bit before I jump ship. I tinkered with it and it worked pretty well.
I think Neovim has tons of potential that's untapped with the Lua language.
