Do you need Duplicator to load BuildBot duplications?
No, buildbot is 100% client sided and only requires that the server allows you to build for full functionality.
Simply bind a key to duplicate, highlight the brick you want to start the duplication with using your ghost brick, and press the keybind.
It would also be nice if it loaded events.
It does, but is not very polished especially in the light that I have gotten next to zero feedback about it.
They way it works is that you:
1. wrench a brick and open up the wrench events gui
2. While in the events gui, press your keybind to open up buildbot
3. Select the build that you want to load events from, then click Load>Load events
4. It will hopefully redirect you to a new gui with a long list of all the bricks in that file that have events, the type of brick, and what events are there.
note: you can access this gui at any time by clicking the new "events" button on bottom of the buildbot v3 gui
5. Select the brick containing the desired events, and click "copy to events clipboard"
6. Close the buildbot gui and you should notice that the event gui is now magically filled with events and the "copy" option is checked.
