Hi,
Is it possible to mix internal and external inputs in a Blockly block? If not how difficult is adding the support?
In my tool ,I need to chain together several blocks with the same type. Right now I’m using blocks with two internal inputs that represent what I need, it works but visually it’s a little wonky because the first blacks’ border wraps around the second, the second block wraps around the third and so on. What I would really like is the ability to an internal input field for the content and an external on for the next block.
I’ve only scratched the surface of Blockly so I don’t really have any idea 1. How difficult the feature I’d like to make is or 2. Where to start to build this feature.
Right now my chains of items look like this:

They're built with blocks I created the look like this:

What I really want is blocks that look like this (created in Paint.net, not the Blockly factory tool):

Can anyone help me either figure out how to make combined internal and external inputs or point me to where I need to start to learn how to build this feature into Blockly?
Thanks,
