Hey folks! Mailspring maintainer here — glad to see this on Hacker News. For anyone just catching up, here's the tldr on Mailspring: - It's a fork of Nylas Mail with the entire mailsync codebase (~40k lines of JavaScript) replaced with a new C++ core based on Mailcore2. It uses roughly half the RAM and CPU of Nylas Mail and idles with almost zero "CPU Wakes" thanks to new C++11 features, which translates to great bat…
Also, where can I look at the sync engine?
