There's been several times so far that I've put stuff in the Cooking pot and entirely forgotten to start the timer when leaving the page. It'd be nice if it had a popup when attempting to leave the page when the pot was full, had at least one valid recipe inside, and did not have the timer started- something along the lines of, “Thumbs calls out, Hey! Did you want me to start this?” or somesuch.
I feel like if done right, this could help a lot with the space-case stuff, but I also can see how done poorly this would be a nuisance, so maybe there could be a way to opt out, too?
