@juliogriebeler said: Hello, i want to load 3 similar extensions with different names and icons. But with all activated in the menu Window/Preferences, in the menu View/Toolbar/ shows only one of them. Anyone know a solution to load the three at the same time? This probably belongs in the Developers' forum ? When you write a new 'tool' you create a toolbar and add commands into it; each commands has its own button images etc... If you have separate scripts loading you need to make an enduring reference to the toolbar. So have a 'loader' script, with a 'module' [say module Julios...... end] in which you define the toolbar with a @tbar = ... reference. Then get it to load the other scripts which you have in a subfolder [perhaps called 'Julios']. Then have each of those script's 'tools' encased in the same named 'module', and have some code to add each tool's command/button to ' @tbar' toolbar. This way you make the toolbar and add items too it from other scripts, by sharing the same module and a common reference to the toolbar, using a @ name that 'endures'
