Hi Daniel,
I have been talking with the PM for the IDE plugins. We are at least going to update the plugin information to make it a little more clear on exactly how to add JRebel plugins through CLI, since it is a little rough to understand currently.
We are also going to consider adding a UI element to the IDE to allow users to import custom plugins via the IDE. We need to do more research on how widely custom plugins are used by our customers to determine how useful this kind of feature would be.
