One UX point: I may have missed this, but when I start an injection attack, it would be nice to see a real-time table of the output so that I can see which injections have been tried (kind of like how you can see it in Burp Suite with Logger++ or the sub-window that opens up when you start an Intruder attack). Totally respect a conscious choice to not go down this (potentially) resource-intensive 'view', but curious if that's on the roadmap. Right now I just get a spinning animation after I hit Run, and I don't see any output in the sidebar where it says "Scans will be shown here once they have started".
In all honesty, I probably will stick with Burp Suite for my bread-and-butter web app testing flow (also helps that my org pays for a Pro license), but I want to thank you for the effort put into this and the courage to explore a new modality (web app testing without a resource-heavy proxy tool like Burp).
