I think the best way for now is that you send me the code (or later on diffs).
I will then commit them to the ROS GUI repository.

Yes, that is right - there is no direct interface to access other plugins from within one plugin.
But of course you can use a ROS topic to exchange arbitrary information.

May be something like this might be added later on - this is still the first version of ROS GUI.
There might be many useful additions which could be realized in the future.

I will working on ROS GUI in the future quite a lot.
So please keep me posted when you work on specific plugins in order to avoid duplicate work.
E.g. a rxbag-like plugin is certainly one of the next plugins to be implemented.
It might be a good idea to fill a feature request for specific plugins to keep track of what is already being worked on.

Since ROS GUI is based on Qt and rxbag uses wxWidgets the actual UI and interaction logic must be reimplemented anyway.
