Added a Zen One "Active Pane Only" mode, a new "Hide Title Bar" option, and some additional error handling.

Added a Zen One "Active Pane Only", or Super Zen Mode, available by Shift + Clicking the Zen icon or activating the additional command palette command.

Added a new option to hide the Title Bar in Zen mode so note text shows all the way to the top of the window (but the Title Bar is technically still there so you can Click + Drag to move around your window).

Added some additional error handlers to prevent unnecessary error messages from showing in the developer console.
