Feature Request: Custom zoom levels and keyboard shortcuts for typing

It would be great to be able to save our most frequently used page zoom levels so we can activate them with a double tap, similar to how the "double tap to fit screen" feature currently works. Alternatively, being able to set a fixed size for the zoom box and keeping it consistent even when changing notes or restarting the app would also work well.

Regarding typing with a physical keyboard, it works great for me, but I would love to be able to change the text color while typing without having to take my hands off the keyboard. It would be awesome to use a keyboard shortcut (hotkey) to select different colors or directly apply different text styles.
