Show findex on currently focused i3 screen

[snaeil]

Is your feature request related to a problem? Please describe.

Using i3wm with two external monitors, findex behaves like this for me:
findex opens always on the same screen regardless of whether it's focused or not.

Describe the solution you'd like

Show findex on focused screen.

Describe alternatives you've considered

Alternatively it would be nice to be able to have configuration options like e.g.:

• open on focused screen only
• open on all screens
• open on specific screen always

That's a nice suggestion! Unfortunately I don't have multiple monitors to test this. Contributions are always welcome!
