Yep, it definately had it, I used it often and it worked great, then the powers that be removed it and now it's not quite as great
Just dug up some old cd's to boot into for a looksee, Debian Jessie 8.7 still has it, Xfce 4.10, Thunar 1.6.3.
Mx-16.1 does not, so it might have been MX-15 I was thinking of that had it, or perhaps even MX-14, whichever MX's were based on Jessie I imagine would probably have it.
Looks like it vanished with the change from Xfce 4.10 to 4.12.
