Add shortcuts for txt notes (checkbox, bold, italic, underline)

Is your feature request related to a problem? Please describe.

On the nextcloud notes app (browser on pc), there are a few shortcuts to create checklist, to make the selected text bold, in italic or underlined. And this apply whether the extension file is ".md" or ".txt".

On the ANDROID nextcloud notes app, I was able to see these shortcuts only on .md files. On .txt files there are no shortcuts and to make a checklist I have to type "- [ ]" which is not the most convenient.

Here you can see when I create a md note and I enter the rich editing mode I have these shortcuts :

Here, when I create a txt note, and I enter the rich editing mode I don't have any shortcuts :

Last question, why couldn't we have these shortcuts without entering the rich editing mode ? Here is the md note with the "simple" editing mode. Could be really nice to have a few shortcuts from here :

Thanks for your time and for the good work !

Describe the solution you'd like

I would like to have a simpler interface where when we create a new note, it automatically shows the shortcuts (exactly as the web browser app).

Start by locating the Android note editor and comparing its rich editing behavior for .md and .txt notes with the browser app described in the issue. Check how the simple editing mode is entered and how formatting actions are exposed. Done means .txt notes provide checklist, bold, italic, and underline shortcuts, with the intended behavior confirmed for both editing modes.
