Button "add/delete program"

how add a button in a toolbar please ?

If you want to add the "Add or Remove Programs" item from Control Panel to an Opus toolbar, just go to Control Panel in a lister, then enter customize mode and drag the item to a toolbar. It's that easy. :slight_smile:

If you just want a tutorial on general toolbar editing:
