Wow I missed canvas support completely. This is going to make some custom UI's way easier to make compared to the hacks I had to resort to in the past [0]
I do hope one day we'd get a new cross platform performant display engine that draws like Zed does for more UI capabilities in Emacs. Neomacs[1] promises this and has some of this but looks like its suffering from never ending scope creep and continuously moving back and forth between 80% there and 90% there due to unattended agents running wild.
It looks like exc.el is built on top of a reactive UI framework, which, well, would have been incomprehensible to the first users of GNU Emacs on PDP-11 UNIX…
Tree-sitter support is quite smooth now, with automatic grammar installation.
Apparently very good Android support.
Canvas support is in master, people are building all kinds of crazy stuff[0] with this
Lots of nice built-in packages like modus themes, eglot, which-key. Editable grep/xref/occur results is also built-in now. New context menu things.
Load the "newcomer-presets" theme to enable stuff that newcomers tend to want enabled (tab bar, fancy completion, lots of little things).
