It would probably be nice to allow people to configure if the URI label should be visible or not. Then if they want some diagram for documentation, without labels, they can export that.

Maybe add a new option in preference
[x] - Show label in graphical editor

The other question on the forum to allow the EIP icons to be resizable, then that's more tricky, as we would need to know the custom sizes that has been changed. And then we would need to store these size coordinates in the XML DSL (which is not nice). So I don't think at present time this is doable. The resize could be a "in memory" only, for people that just want to resize and layout diagrams nicely for documentation purposes which they then export.
