some quick feedback on the user interface:

- i pressed "Amino Acids", and nothing updated below the toolbar. can't figure out what it does

- the "Tools" buttons looks like a segmented picker, but both seem to actually initiate a modal presentation

this tool seems interesting, but it would be worth polishing some of these ui quirks because my first impression was that it seems a bit broken (or confused me)!

but seems like a cool project otherwise, love people building and sharing explainers as they learn stuff!
