I have two displays on my Mac. When I invoke Alfred, the search window appears on the right-hand display, which is where I dragged it to.
If I then press ⌘, to open Alfred's Preferences, they should appear on the same display as the search, since that is where I was looking. However, they appear on whichever display had the focus before I invoked Alfred. Despite dragging the preferences to the right-hand display, the next time I press ⌘, the preferences window ignores that explicit drag and opens wherever the focused app was.
As it's possible to configure which display the main Alfred window appears on by dragging it, please could the Preferences window either follow it, or remember when it has been dragged to another display? It's a pain to have to go hunting for it (probably even more so for people with more than two displays) and especially when it opens on a display that's too small for large workflows without a load of scrolling…
