Minor interface redesign

[kael-shipman]

Hi there!

This is an awesome app and I'm using it to control my raspberry pi home theater. Working great so far!

I just have one little adjustment I'd like to request. It would be great to just anchor the text input box right to the bottom of the mouse screen along with some essential buttons like tab and enter. Then the toggle button would just toggle between the mouse screen and the full range of buttons, but the text input and enter and tab would always been there at the bottom regardless of which screen you're on. Here's a very rough screenshot:

Also, I'd be willing to fund some specific development on it if you were up for that. You can find contact information for me at https://colors.kaelshipman.me/about. Lemme know.
