Feedback \ feature requests

Hi! First of all thanks for the app, it looks like something that might actually work for me.
I have a couple of suggestions \ requests, please consider:

1. A way to hide "hint" message in window mode, aka "click Shift ...", or only show it when the window is hovered on
   
2. Change font size when you scale the window, let's say I want to have a bigger window on my 3rd display, font-size should match the size of the window
3. Custom changing speed
4. Remove word ID from the window, if you want you can keep it somewhere at the left bottom, semi-transparent
5. Stop changing words if the window is hovered on
