Performance of AppleScript Ubersicht refresh

[camspiers]

I found that the refresh of widgets via AppleScript was too slow. It turns out it was quite an effort to do it another way, but I came up with a solution that you might be interested in:

New program to get active space changes from stdout:

Build step:

SSE server for delivering SSE's to Ubersicjt widgets:

Subscription to it from a widget:
