add built-in commands and "s/keyword/new word" editing, and "+:emoji:" fast-reacting, and matching formatting style to other plaftorms

I KNOW you said that those were a "dead cause", but come on? do you really want your platforms to be unbalanced? Plus, there are some formatting tricks that only happen on IOS and Desktop rather than on android, which, considering that only 2 developers worked on ios, but there's a whole team for android, is just pethetic. Thank you, hope you balance out all of your platforms.
