I agree. ideally, it would allow for notes and tasks sync with home cloud solutions like nextcloud.
Tasks-org is a gas factory and opentasks is not maintained since 2021

With DAVx⁵ also possible to connect e.g. with DAViCal and more.

[daffydock]

Agreed. Using DAVx5 should be a far easier implementation that could cover a number of services, including Nextcloud and others.

Ideally a clear distinction of VTodo and VJournal specs akin to JTX Board.

It looks like many people want this feature. "Problems" I see:

• This is also requested in the Calendar app (and I think it's more appropriate there)
• If this is done, sooner or later someone's going to request for task repetition (also available in Calendar)
• Fossify Notes is supposed to be the simple(er) notes/tasks app.

I'm not dismissing this request but I'm also not sure if it aligns with the app's current goal.

i see your point...
i'm mainly using synced tasks for groceries and simple checklists, but as you say, it may be better to have tasks in a separate app instead of inside note app...

When using Getting Things Done it is considered bad practice to add a date time to a task. In that case, better create an event in your calendar. IMHO tasks in a separate task app should have no date time functionality, even though the ICS file format supports that. You would like to guard the scope of task and calendar app.

If people really need it, they could be helped with a function that converts a task in the task app into a calendar event in the calendar app and deletes the task afterwards, in the task app. Similarly, a calendar event could be converted into a task from the calendar app to the task app.
