hi! some constructive criticism.
i love the idea, connecting developer tools via a plugin to the site is genius. this is a very creative way of doing this, and it's perfect.
the user interface on the site is pretty messy though. i've just tried to fetch my first data and it just got to messy to be worth it. it's currently (for me at least) less messy doing this sort of thing manually than clicking around in the interface, and that should give you a hint that the ux needs some work.
will check back in the future though, it looks very promising!
