Here are mine (currently I'm on SlimKat, on JB I used some more)
Boot manager --> decide which apps that can start at boot
Custom Share --> decide which apps show up when you push the "share" button
Instagram Downloader --> makes you download instagram photos directly from the app
MinMinGuard --> Ad remover (in apps and on the browser)
AppOpsXposed --> bring back AppOps
YouTubeAdAway --> it's in the name
xMultiWindow --> adds multiwindow-like view to any rom
Greenify --> it's not really an xposed module but you get some extra features
GPS notification --> apparently when KK doesn't have th GPS notification icon, this brings it back
Map zoom invert --> inverts the zoom movements on google maps
Play store link in app info --> it includes a button in "app info" that takes you to the play store entry of the app
