Thunderbird for Desktop, while far from perfect (nothing is), is a promising piece of software with Email, Card/CalDAV and ICS synchronization, tasks, OpenPGP, RSS, Usenet, IRC, XMPP and Matrix support built-in into a single app.
On Android, in order to replicate this experience, the user needs to install dedicated, separated apps like: DAVx5 for DAV integration, OpenKeychain (which has ceased development) for OpenPGP, dedicated feed readers for RSS and Usenet...
It would be great if Thunderbird for Android reachs feature parity with the Desktop version at some point in the future, at least when it comes to CardDAV, CalDAV/iCal, OpenPGP and RSS support. An equivalent to Firefox Sync would also be appreciated, especially if it allows synchronization of local address books, calendars, public PGP keys and/or RSS feed lists without resorting to dedicated servers.
