Obsidian force note view mode
This plug-in allows you to indicate through front matter that a note should always be opened in a certain view mode. This is done through the key obsidianUIMode, which can have the value source or preview.
Add below snippet (front matter) to your note ...
---
obsidianUIMode: source
---
... and this will force the note to open in "source" (edit) mode.
Similar, ... add below snippet to your note ...
---
obsidianUIMode: preview
---
... and this will always open the note in "preview" mode.
This plug-in also ensures that a note is always opened in the configured default mode (suppose the Obsidian setting has "preview" as default mode but the pane is currently in "source" mode, then opening a new note in that same pane will open in "preview" mode).
