When you plant flower seeds, they are currently offered up in a fixed order, with the very first one highlighted. This is annoying if you use the arrow keys to choose which seed to plant. For example, if I want to plant 16 silvertongue seeds, I press up to move to the next plot, enter, and then left three times to highlight silvertongue, repeated 16 times.
What should happen instead is that the seed arrangement should be something like a stack, in the sense of the data structure, so that the more recently you've planted something, the less keypresses it takes to get to it. Failing that, the last thing you planted should be what starts highlighted. Saving 45-48 keystrokes every time I plant silvertongue would make me happy. :)
