version:
0.1 - 26-27.2.2004 - write all from scratch
0.2 - 3.3.2004 - speed up filling listboxes
some ergonomic fixes (like stay in category after ADD)
fixed possible language problems
0.3 - 27.3.2004 - rename action > actualise editor
0.4 - 29.3.2004 - dblclick generate xxx.OnExecute code to editor
0.5 - 10.03.2005 - New design
0.6 - 14.03.2005 - multilanguage support
TODO:- multiselect for the actions and categories
- drag & drop for the actions and categories
- standard icon for "Standard Action"
- sometimes click in listbox causes selecting last item
(it's an strange gtk error. The LCL and the gtk intf do not send any
change to the gtk. Either it is a bug in the gtk1 or we are doing
something wrong in the handlers.)
