Okay, I fixed them.

Should I create patch from previous one, instead of whole patch?

It's just my mistake, I deleted.

I used "Display ID" as index for screens (0, 1, 2, ...), not actual CGDirectDisplayID,
so I think stepper is enough for it, but, as you said, it seems that it's confusable name.
I changed it to "Screen Index", and make "Display ID" actual CGDirectDisplayID
(leave them for command-line argument, user no longer have to consider them while using GUI)

> 2.1) I'd implement the Display ID selection the other way around, similar to the simple preferences window. There, we display a list within a popup button with "Screen n (%i * %i)" (width, height), so the user actually see which display s/he wants to select. Internally, you map the selected screen to the gained Display IDs and forward that value to the access module.

It's a nice idea, I changed the field to popup.
