"Only current window" by default

[levouh]

Is your feature request related to a problem? Please describe.
When opening/using Tab Butler, if I only want to search tabs for the current window I have to select the box each time. My main use case with this plugin is to avoid using the mouse, so it would be nice to have the ability to have "only current window" be the default.

Describe the solution you'd like
Configuration option to have "only current window" be checked by default.

Describe alternatives you've considered
Key binding to toggle this option, to avoid having to use the mouse.
