Well, it's much improved, but now (and this is insignificant in the scheme of things), the splitter actually migrates very slowly up instead of down, probably 1 pixel for every 2/3 ASR open/close iterations. In other words, you really have to look for the difference, and maybe within six months a pedestrian user might lose the height of half a line.
I only notice it because I prefix my custom presets with "_" underscores to raise them to the top, and that character acts as a horizontal line marker in this case.
I doubt too many users would ever even notice it - in fact, it only seems to happen if you adjust the splitter at all initially (at its lowest placement it appears static), and considering it's invisible in the first place, how many people really do that?
Thanks.
