Is your feature request related to a problem? Please describe

For note taking I don't think it's that useful to have two tabs open for the same file. That takes up more screen estate and leads to the indecisiveness of which pane to look at when reading through / editing a note.

The fact that one's notes will never be a "finished product" doesn't help the case of a dual pane either. Not saying get rid of it, because there may be people who use Dendron as e.g. a site generator (on top of this being a matter of preference), but having an option of not having to deal with two separate panes would be huge.

Describe the solution you'd like

A (pseudo?) WYSIWYG mode like the one in Typora and Obsidian.

Describe alternatives you've considered

There's https://github.com/ryanmcalister/unotes but it lacks Dendron-specific features. E.g. mermaid is not a thing there. Neither are note references.

VSCode comes with a pseudo-WYSIWYG mode, but, again, lacks the Dendron-specific features, and while it does support things like Katex or tables, it doesn't help construct them or add any helpful pseudo-formatting so you're pretty much forced to use the preview pane with those.
