I have a blocker on plugging it in, though: we're a Microsoft Exchange shop. Now, it's easy to sync Exchange to my Mac calendar, but it is not easy to sync Exchange to Google calendar. (Googling, seems like the most reliable way is to PUBLISH your calendar... something I don't think my security / IT folks would appreciate.) I could also use Zapier it looks like, but I'd quickly run over the 100 tasks/mo in the free tier.
I have nothing against electron—power to you for solving a real problem I have, and using javascript to do it quickly. But I do think popping open EventKit to hook into the system calendar would be a solid next feature. Then people like me who are locked into Exchange will be able to use your product without ugly/brittle/security-degrading hacks.
