Hihi – just introduced Hydra to my students today and have the following two suggestions (can easily say 'NOOOO WAY!' and close this.. haha just ideas):

• give the landing modal box a ~50% opacity to the background, so we can still enjoy the visuals behind it, rather than only the bits that peek out from the sides.. ie within #modal background:rgba(0, 0, 0, .7);
• add a transparent div behind the modal, that if clicked on, closes it – rather than needing to press on that that X, so one can jump right into coding quicker.
• list the shortcuts within the modal, so one can quickly know how to toggle code, save outputs, etc.
• could be nice to have the trashcan icon also on the modal's upper right icons, so one can jump right into coding from scratch at the start? unless there's another trick to opening the editor with a clean slate? or something like https://hydra.ojack.xyz/?new or https://hydra.ojack.xyz/#new
