I will have to give it a try 
Does it have the MacVim niceties? The nice thing about MacVim is that it is close to a standard Mac app, with the standard shortcuts etc, CMD C/V, A, S etc 
Ah I keep forgetting that - thanks! ODL mentioned it on Devtalk a while back too.
I just downloaded it and it wants to connect to Vercel (as well as openvsx - which is expected):
(I will look into it more when I get 5 mins tho!)
This might be the updater process: Connection to 76.76.21.21 on startup · Issue #895 · VSCodium/vscodium · GitHub
I don’t do heave IDEs for Elixir since normally it is multilang project for me (elixir / python / js / whatever else).
I would say the best IDE really depends on what OS you’re working on. For Windows options (in my opinion) are limited, since it is just easier to run Elixir under WSL/WSL2, which leads you to VSCode + elixir-ls.
Hovewer my favourite editor is Sublime, VSCode tends to slow down with every release and I can’t stand slow working tools, it feels really unproductive.
