Actually, we can't show where we have a corridor transition without being inside the command corridor transition.
Problem : If somebody work on your corridor and dont know you used transitions, that can create some mistakes...
It can be really interesting to be able to show in plan view where we have these transitions by using for example the corridor style with an ON/OFF button.
Showing where we have a transition is very nice but if we can have the description of the transition automatically of/and by writing a description by ourself to explain can be better.
An other solution, or a complementary solution can be to show the information of the transitions in the "Parameters" inside the "Corridor properties" next to regions,...
