> What does vim support inside a block editor means?
Users who care deeply about note taking want don't want to learn a new set of keyboard shortcuts and movements. Apps like Logseq and Obsidian (and many others) either support Vim-style movements out of the box or they're available as a plugin. Same thing with Emacs-style shortcuts and Org mode.
Folks have been using these editors for decades and they want to use their muscle memory everywhere they enter text.
Depending on the user and the use case, the lack of Vim or Emacs support ranges from a minor annoyance to a show-stopper.
If that's what OP meant, then no. Plume will support the basic keyboard shortcuts expected from a text editor, and then some more. My previous note-taking app[1] is already very keyboard oriented, and I intend to do the same with Plume.
EDIT: Just noticed that most of the "Cursor movements" already have equivalent standard keyboard shortcuts in regular text editors.
