Doesn’t building a front end with a kit as heavy and unwieldy as Electron kind of defeat the purpose of a small, light console editor like vim/neovim? Don’t get me wrong, this looks nice, but if I were a (neo)vim user I think I’d be far more attracted to a front end as light as (neo)vim itself.
I get where you are coming from, vi and vim being rooted in low bandwidth light interfaces. However, I think a lot of vi/vim users would like a more fully featured IDE that had the power of vi/vim in terms of usability.
Given the number of vim users I know that install a dozen plugins, I'd wager you're right. Surely, I can't be the only person who uses stock vim, though.
I use both. I have my vim IDE-like with a fair number of plugins. It's my kind of "IDE environment", and for this I would love to get those kind of integrations.
But whenever I have to open a large file, or just make a simple edit to a file on a server, I have a very simple vim with no plugins and a very small vimrc that should work everywhere.
To me, the appeal of VIM is not the lightness, it's the editing paradigm it is based on. I won't be switching to this any time soon, but I can think up plenty of nice features that a html-based view would allow over the terminal, and I wouldn't mind paying (a bit of) a price for it.
The screenshots don't show anything that couldn't be accomplished with a regular text console either, which certainly doesn't help show why anyone would want to effectively run a whole browser just to emulate a terminal.
At the very least, the other "web everything" projects I've seen show something that wouldn't be possible with just a text console.
