Option to disable rich text editing mode

[AtomToast]

Is your feature request related to a problem? Please describe.
I am used to just writing out markdown symbols like for example [link](address) for links. I mainly use the nextcloud editor to check or extend my notes when not on my own machine and the fact that I can't just simply edit the plain text in the file is frustrating. Having to learn those shortcuts or pressing the buttons is a lot less convenient than just typing everything out or being able to edit those symbols directly.

Describe the solution you'd like
Just have a toggle button or setting to switch to switch to a plain text mode, or even better an edit mode, similar to the one you can use in the notes app (which seems to use the same underlying editor?)

Describe alternatives you've considered
Move all my markdown files into notes so I can use their editor. Though then I have vastly reduced support for subfolders.

I also wanted to complain that expansion of markdown symbols in general didn't work for me but I must have done something wrong until now, since when I went to take a screenshot it actually just works now lol. Not sure what changed but I swear, right before this, typing `code` would result in \`code\` in the file. Or starting a line with - or ## would not result in a bullet point or heading. I even downloaded it to check when debugging this issue. But that definitely reduced friction and a big part of my issue now. Biggest annoyance left is really just links

This is would be a really important feature, being able to see the markup in text. Some kind of sytax-highlighting/rendering the text accordingly is of course good feedback for the user, but it shouldn't hide the markup.
i would add: linenumbers in such a (hybrid/)plain text view. :)

Dear @AtomToast, thanks for your feedback. Markdown editing is indeed a long requested feature. Unfortunately it's pretty complex to implement due to interference with the collaborative editing synchronisation.

The feature is already discussed at #3570, closing this one as duplicate.

Regarding adding links with markdown syntax, there's also #55 to track it and it might come to Text soon: #5894
