- There is no way to disable auto-formatting behavior when pasting on iOS/iPadOS
- Pasting text when cards list is in the focus creates new card and pastes the text in the body of the newly created card. This may be a feature, but this is confusing, because starting typing adds text to the title of the newly created card (not the body)
- Pasting in the body of the card is not counted as undoable action: for example applying undo after pasting in the body deletes title of the newly created card. Here is the video.
Shift+Cmd+V hotkey (paste plain) does not works on my desktop Safari (Big Sur). Fortunately hotkey Opt+Shift+Cmd+V (which is set in Safari to ‘Paste and match style’) works exactly as needed: pastes the clipboard contents without modifications.
Now I want to find some workaround to be able to paste plain on iOS/iPadOS…
Personally, I’m not quite happy with the ‘magic pasting’ of links.
For example, here it is how links are currently ‘magic pasting’:

supernotes.app
supernotes.app
Not informative at all, right? Below is how this forum handles the same links (without any ‘magic pasting’):
Can we have something like this (with this well-known SN attitude) instead of just putting the domain name as the name of the link? 
Or, maybe, something like this?
