Performance is poor on my older laptop. Maybe I'm getting to the point where web devs should leave me in the dust, but, it's also a shame to waste resources on newer systems. I suspect the problem is that it's built on React, which struggles with large data sets.

If the team is reading this, I'd bring up a point made on the Netflix dev blog: the key to great React perf is doing the expensive stuff outside of React. Do it low-level, stitch it in with lifecycle callbacks. You can end up keeping most of your code in React's world, while fixing most of the performance problem.
