This is a compelling product pitch to me - I alternate between using vim but not having everything memorized, and using GoLand for its autocomplete and various correction/detection/auto-import-fixing conveniences but wishing it were faster.
I'd be willing to pay $5/month for a beta version, if I were using windows. Or alternatively, if someone is watching, I'd be willing to pay $5 for a trial of a mac version :) Respect it's quite a bit of work to support a second OS and window manager and you have to start somewhere - Hope it goes well and makes its way over to Mac soon!
