Hello,
I, too, would love to have a CalDAV standards-compliant task app in Sailfish. On my libre Lineage OS device I use jtx Board because its standards-compliant and plays nicely with Thunderbird’s task management on my laptop. But I would prefer using Sailfish OS as my primary mobile, yet the lack of tasks integration holds me back.
I’m a little unclear on the above details in this thread: does a CLI interface already exist for tasks via Sailfish’s CalDAV sync, and we only need an app built?
A separate task app would be fine with me, though I could see an argument for calendar integration. But if the calendar is part of the closed-source bits, have there been any attempts to build an open calendar app with similar UX to the existing calendar? This would enable the community to improve it.
