Hi, friends! I'd like to build a module
The goal is to modify the default roll dialog to add an additional button. Alongside "Advantage," "Disadvantage," and "Normal," I'd like to add a button to trigger the "Emphasis" roll, a mechanic which rolls 2d20 and takes the result farthest from 10. It's a mechanic my players really enjoy for high-risk situations.
I have a macro working as a quick proof-of-concept which emulates the behaviour, but I'm not sure where to start in terms of modifying the built-in roll dialog so I can do it in a less hacky way. Any ideas?
