The X-series pups (Precise, Tahr, Slacko) offer right-click menus in the main menu and dragging to the desktop for launchers.
'Course in JWM right-clicking is the same as left (apps run).
I've recently learned the right-click menu is not a default feature in XFCE, yet I have no idea how it is enabled.
There are XFCE versions that run apps with a right click just like JWM.
Another non-standard feature is app search and custom launchers in the menu.
Control Panel, Pfind, XLock, Logout are right there.
Excellent functionality
