iPad/iphone Augmented Keyboard?

Hi. Thanks for the app!,
Is there considerations for adding an augmented keyboard for a
Joplin? I’ve found some of the standard characters used for functions, such as dashes for table creation and sequence diagrams (unless Mermaid isn’t built in?), just makes a solid line instead of a dashed line with Apple mobile devices - I thought it worked correctly a while back, perhaps an Apple update borked it. Maybe an inserted augmented markdown keyboard above the device keyboard would alleviate changed Apple decided to apply.

Row line numbers could be super helpful too
