There is a tremendous need for a minimalistic chromium project that would coexist well with the Linux Tiled Window Manager ecosystem.
With downloads passed outside the browser, favorites stored in some sort of JSON and support for native WM tabbing.
"tremendous" might be overstating the market of all 8 suckless surf users
There's only 8 of them but they need it real bad.
What about qutebrowser? It's based on QtWebEngine (a sort of ungoogled
chromium), has a minimal UI, extremely customisable and can be extended with
userscripts (nothing to do with js). You can do stuff like editing textareas in
your editor by spawning a subprocess, open a video with mpv, pipe something to
dmenu.
