Modifying activities in debug

Something that would be awesome, is to be able to modify your activity flow while in debug mode! And perhaps change Locals on the fly aswell.

I understand that there might be some challenges with this since I guess the run is already compiled in some way when starting, or however this works.

But looking only from a developers perspective… It would be great and save lots of time! You wouldn’t have to start all over every time you add something and you could build your process while testing. It could be restricted to some type of activites, if it makes it easier.
