Since the old ROADMAP.md is hopelessly out of date, and probably not the best way to track that moving forward, given our shiny new Discourse, I’m just dumping the still-active feature plans here for now:
Goal: Build a beautiful CalDav and Google Calendar interface that can be opened in a new window or as a tab in the main window, making Mailspring a full replacement for the calendar-contacts-email suite.
Goal: Allow users to sign outgoing email with a certificate, and verify the signatures of signed inbound email.
Goal: Make it possible to use a Template and a spreadsheet to batch-send emails with open / link tracking. Nylas Mail used to have this feature but the implementation confused users and didn’t handle sending errors well. The new version will
Theme and Plugin Browser
Goal: Make it easier to download and install community themes and plugins from a trusted, centralized “gallery”, like the Chrome Web Store. (No immediate plans to allow to enable paid plugins.)
Goal: Move Mailspring to a newer Electron release and make the necessary changes to support it.
Goal: Make it possible to connect and sync any IMAP account with Mailspring. The project is close but still encounters sync issues with small or unsual IMAP providers.
Advanced Mail Rules
Goal: Replace Mailspring’s built in contacts list (which is based on email headers) with one that uses CardDav and syncs with Google Contacts / O365 Contacts and allows full contact CRUD.
