Gavin.... Many users already told you they does not use your plugin because the most important feature, the CTRL+R switch, DOESN'T WORK !!!!
I've already told you that: your project looks like abandoned, you even don't answer to issues...why someone would use it ? I use your plugin because I've patched it and it works great, save a lot of time in switching, etc.... but since I don't know anything about eclipse development(and I don't care about that), finding the bug took me 10 minutes, but finding a way to build the project correctly made me loose a lot of hours ! Why don't you apply the patch, mark the issue closed, make a new build, and yell here "hey buddies, now it works, all you have to do is install it" ? I'm sure you will gain a lot of users. Cheers, Giulio
