Edge's 'read aloud' is also excellent; I haven't found an alternative browser or extension that sounds as natural.

The fact that it works with PDFs is helpful for proof-reading, too (especially when it highlights each word it reads).

Have you used DifferentialEquations.jl? From my reading, it seems to be the most performant solver out there — and I personally love using Julia and its ecosystem. There are some really interesting talks by Chris Rackauckas about what's possible with DiffEq/SciML packages — ModelingToolkit.jl seems especially exciting for automating the development of scientific simulations.
