The timeskip mechanic works - I'm not denying that at all. Admittedly, at first I thought it was bugged but reading a similar issue on the forum proved otherwise. However, in its present incarnation it's a tad non-obvious and doesn't provide much affordance about its functionality. What I propose is that the red-scrollbar-then-click-on-the-interval-to-select mechanic is replaced with a down arrow button, which opens a drop-down list, and possibly a select button under five or six rows of options if a confirmation is still required or desired. This revision would provide the affordance that the previous system didn't. It's a small change, but an ergonomic one, and low priority at that.
