RE: feedback mechanism -- yep, a feedback mechanism is definitely something we're thinking of adding. Since we use VLMs that are trained to always output coordinates (i.e., they don't have a way to say "not on the page"), we're probably going to try fine tuning with some negative examples to see if we can build that feedback mechanism in.

One way to hack the scrolling to an element is to first run extract_bbox on a natural language description (in your case for GitHub it might be "follow button") then take the Y coordinate of that element and scroll that number of pixels. I just wrote this bit of code that I tested and it brings the contribution graph into full view:

    simplex.goto("github.com/spro")
    coords = simplex.extract_bbox("follow button")
    simplex.scroll(coords[1])
    simplex.wait(2000)
    image = simplex.extract_image("green tile graph")

re: frequency graph typo -- just pushed a fix, thanks!
