Thunderbird in 2019
I love thunderbird because it's the only email client that does everything I want. I tried CLI clients, they are great and customizable, but CLI is a bit bare for email (images, html, fonts...)<p>Things I'd like to see improved:<p>- Native CardDAV and CalDAV support (there is caldav, but no discoverability of calendars).<p>- Native PGP.<p>- Better search, the UI is horrible and the search string is hard to get right (need fuzzy search and partial contact completion).<p>- A bit of UX work, some preferences are just a nightmare to find.<p>- Automation (auto tags, auto threading (for example, I get an order confirmation from webshop X, and a while after a shipping confirmation from webshop X, I want those to be grouped)).<p>- Improved storage engine, thunderbird is often freezing to compress folders.<p>- Critical bugd being fixed, like "imap"->"local folder" messages vanishing.
