I know I could learn it easily, but I was not thinking in my personal situation only, I think it could be usefull for a lot of users. If we are talking about free and open software, you could always modify or ask someone to modify an object or an actor that you want change because it doesn't fit your needs.
I also think that a graphical user interface makes programming faster.
Hey, but what about code and graphical user interface both in the same arduino software? I still find as a big big feature
Mytx,
You are correct, the barrier to learning graphical programming vs. textual is significant. If powerful graphical programming interfaces can be made or brought to Arduino, it will accelerate adoption of the platform.
Cheers,
