A long pending request from swtbot users has been support for GEF. The SWTBot4GEF project was created as a sandbox to see how feasible things were in the GEF world.

Mariot Chauvin recently polished the initial contribution from David Green and released a version 0.1 of the gef support. We’re working towards integrating this as part of swtbot and you should hear more about it once the IP process is done :)
