I'm looking for a way to represent a system in the form of balloons, flows.
I thought about using UML diagrams, I did a part, but I came across a difficulty, to expand specific things. Without opening screens and more screens.
I am looking for a tool that allows me to expand balloons, which go from general to specific, but do not lose sight of the general view (opening screens and screens).
Suggestions?
I've already used MindManager and Astah, but I came across limitations.
