Linux Lite 3.0 Final Released

[Mike]

But in LL 3.0 it's missing & the right click option to minimise from the panel button is greyed out.

This may have been a change in Xfce 4.12 which LL3 is now using. I believe you can hide the window by clicking on the folder icon in the notification area. Not sure why they hid the minimize button in the transfer dialog though...seems odd.
