I’ve been playing with the obmenu-generator for a while to have a look into that.

The menu looks and works great, so I decided to move it to Sparky’s Openbox Editon instead of the standard Debian menu.
It gives options to build a static or dynamical menu, with or without icons.

Obmenu-generator

Installation:
sudo apt-get update
sudo apt-get install obmenu-generator

It needs ‘sparky-editor’ package, version => 0.1.7.

Installation of the ‘obmenu-generator’ package will install all needed dependencies, and will set the new menu automatically. The older menu will be moved from the file:
~HOME/.config/openbox/menu.xml
to the backup file:
~HOME/.config/openbox/menu.xml.bak
if you’d like to restore the older menu back.

It also set the static menu with icons as default.
It can be changed via the pipe menu after installation as you wish.
