Missing autofocus in dialogs since Sketchapp Version 53
Until now, when I hit the keyboard shortcut to open Sketch Mate's Dialog (for instance Smart Align), it was in autofocus, so that I could go ahead and type my value and hit enter.

Since Version 53, I'm missing the autofocus:

Also: I'm not sure, but I think before, there was no prefilled value in the input field. Now there is a "0".

It would be so great, if the autofocus in the dialogs would be there again and if there would be no prefilled value, like so:
