Great tool, thanks! It's quite helpful.
I used google translate to understand how to use it and it worked surprisingly well, you explained everything so good.
In case you're willing to work on this more, as a suggestion, you could add color coding (matching colors for keys and locks), or a button that resets the diagram directly without needing to go back and click on generate again?
Idk, these are just quality of life changes, the software's really good as is to be honest. I'm trying to put it to good use.
Cheers 🍻
