I second that, really nice improvements the last weeks from your sides. But indeed, the air is getting thin so it is hard to get higher in the ranking/APS. Although my big changes, to be able to use BulletShadows, are a bit postponed due to failed preconditions (0.3.21-0.3.23), fixing/improving some small stuff when you encounter them can also be satisfying. I rather fix things and then take the big step, then the other way round, because that big step will blur the things to fix/improve.
I'm mostly doing this right now. While developing Roborio I could take a glimpse of what it is like to do a feature-driven development, and it certainly haven't paid out. When I rewrote the code I could find a dozen bugs lurking around my gun and my movement and eventually Knight became really different from the former just because of those bugs. To avoid losing my motivation (which is very important as well, we gotta have fun at the end of the day), I'm interpolating fixes/tweaks with new features/experiments.
