This is very cool and looks like it could be extremely useful. Maybe worth trying to integrate into rostopic echo itself, I.E. by passing an extra flag or something. Might be worth going that route with ROS2 since I see roshow2 is still in the TODO phase, though I realize that's a whole can of worms.

If the core ROS people are interested in integrating it I'd be happy to discuss, but if that doesn't happen I don't think they expose an API to control the behavior of the rostopic command.
You did give me an idea though which is to have rosshow "fall back" to rostopic echo for types it doesn't understand, so that you never have to "try twice".
For ROS 2 support -- I abstracted out all the Viewer logic from the ROS logic so in principle it should only take modifying 1 file of code and maybe some package configuration changes to support ROS 2. I'll work on this after I familiarize myself with ROS 2, or would love community help here.

Expose API? I am not sure why that is necessary? The source code for rostopic is here:
https://github.com/ros/ros_comm
What is the barrier to simply adding a 'plot' command to rostopic?
[edit to add:] Ignore the naysayers, this is an excellent tool. I am sad I missed the demo Wednesday night.
