We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
Salman, I am assigning to you. There's a lot here, don't consider it a monolith - you can chip away at it. I'm aware it may conflict with some of what you have been doing, so you can consider it with your discretion and we can always discuss it.
Also whether to have the scroll-in-place (stuck_nav in v10) on.
