I think it could be interesting, as someone who uploads sparsely, to add a little marker for timelines on days where you upload, and maybe provide a list of what you did upload. I can generally guess when I uploaded because of the spikes, but sometimes it's hard to remember what I did upload or update at the time of that spike.
Maybe, also for general statistics, it could be cool to see total stats over time (without their sources), to see growth better. Might get funky if scale is too large either over time or numbers, but would be an integral function.
So far been good, I feel like I'm able to navigate the analytics page well and make it what I want so well done! =]
