[FEATURE] Simple interface for phones

[LeonelRFF]

Description of the Problem

Creation can be slow on cell phones. I refer to this because of the lack of buttons that allow you to create formulas. In other words, since it is a virtual keyboard, accessing the necessary characters that are usually hidden slows down the process of use.

Description of the Solution

Implement shortcuts that can be added in "mobile Quick action" Just as when you press the title button, additional options open to use more options, in this way it will allow a more practical use from mobile devices, similar to what there is in the online latex editors, but of course without leaving the app

Additional

• Use the command palette to enter certain settings
• Another long-term option could be a simple interface to facilitate the process, although this would be more difficult

I don't know if there is a way to implement this with the Note Toolbar plugin, as I say this is more practical on mobile devices

Regards.
