[FR] Hide Cursor/ Change Cursor Opacity, Color, etc.

[filipgoc]

Hi! Thanks for a great package.

I bring a suggestion. For a truly ZEN experience, it would be nice to make the cursor less distracting than what some themes do. Many have blu blinking cursor for dark background etc, which is nice for code editing, but for ZEN writing, being able to make the cursor almost invisible would be nice!
