My interpretation is that when switching between insert mode and normal mode in Vim bindings, the request is that Obsidian automatically switch between… I guess Source Mode and Reading Mode.
Sorry ivancan, but this does seem a bit weird to me. Because Vim doesn’t have a “navigation/view” mode. In Normal mode, you are still quite capable of making (powerful) edits to the text. It’s kind of the point of Vim. And switching automatically to Reading mode would break that functionality.
There is a partially-related request to enable j and k as a scroll option in Reading Mode. And koala made a plugin to do that. Navigating in Reading Mode with Vim plugin (no accidental editing possible :) - #20 by koala
