@jarbesfeld and I are reviewing together. It looks great!

Some suggestions to address in future issues:

• Maybe consider having a smaller scrollable box for genes that have many transcripts
  
• @jarbesfeld suggested labeling which transcripts are MANE select/clinical plus in the dropdown
• Some larger transcripts get cut off

👍 looks good. I think we could consider (?) reversing the order that transcript options appear in the dropdown, although it seems like the right one tends to be preselected, which is probably enough.

added this to the issue where we'll display MANE/clinical plus transcript catergories on the dropdown!
