For sharing via GistPad: a great start, but ultimately I'd love to share with people without VSCode via hosted URL. There's an excellent bl.ocks.org that can render Gist in a browser (just replace gist.github.com with bl.ocks.org if you have index.html file: https://gist.github.com/methyl/f4c2395f941493b6bf5212dac5e44... => https://bl.ocks.org/methyl/f4c2395f941493b6bf5212dac5e44b2c or if you prefer direct link add /raw https://bl.ocks.org/methyl/raw/f4c2395f941493b6bf5212dac5e44...). I guest GistPad integration could generate those sharable links.
I also noticed there is a preview mode in GistPad. How does it differ from CodeSwing?
