myStuff

Description
Create a custom menu in a popup window. Drag main menu entries or desktop launchers into the window. Alternatively, use a GUI to specify menu text, icons, and command lines. Arrange the menu layout by dragging entries with the mouse. The resulting popup menu can be started from a desktop or panel launcher. The popup window disappears or stays put after use, depending on a flag set for each menu entry.

After installing, use  $ man mystuff  for user information.
