Persistent FS Preview and/or Single-monitor Desktop Preview

[morpheus867]

I have a second monitor that is excluded from desktop switching. I'd like to have the desktop preview up on this monitor all the time, but have it show only the items on my primary (multi-desktop) monitor. Even better would be to be able to keep the full-screen preview window for monitor 1 visible all the time on monitor 2 (but not necessarily full screen).

I'm pretty sure I could hack together the second option with Actual Window Manager or AHK, but it would be great to have an official option.
