Feature: formatting options in selection (iOS ?)

Like the "Mark as spoiler" in the options when a text is selected on mobile, could other options can be added ? Like Bold, Italic, Code, Code Block, etc... ?

Because searching special characters in the keyboard on the device (without external keyboard) is not very easy to do, and the OS sometimes do auto-replace, and it's taking a lot of time to format a text on mobile.

But doing like the "Mark as spoiler" in the selection would be awesome for other formatting options !
