(シャトー・ダニエル)Well, this looks neat. Might need to try this soon.
Normal Mode@djchateau Looks intriguing, but I just tried the solo version and it doesn’t accept most of the Vim commands I tried. The tests seem to be tailored to fairly specific solutions which aren’t always the ones I’d naturally use.
Hopefully they continue working on it to make it more complete!
