Modify roles of ressources

Hello
I am using Gantt project for my private business.
I would like to modify roles of ressources ( for the moment, they are dedicated to software development).
Why role definition is not customizable?
How can I create my own roles list?
Thank You
René

You can add new roles on per-project basis. Project > Properties > Resource Roles

It is possible to add new role sets which appear in New Project dialogm but it requires editing .ganttproject settings file manually. .ganttproject is an XML (basically, plain text) file and you can edit it in any text editor. Find a group of tags <roles>, make a copy of it and define your own roles:

    <roles roleset-name="Default">
        <role id="0" name="undefined"/>
        <role id="1" name="project manager"/>
    </roles>
<!-- BEGIN CUSTOM ROLE SET -->
    <roles roleset-name="MyRoles">
        <role id="0" name="undefined"/>
        <role id="1" name="Superman"/>
    </roles>
<!-- END CUSTOM ROLE SET -->

It works, albeit I can’t say that it works perfectly.
