Tasks.org has cool filter system, which alongside it's widget makes me list of everything that's important to me just on home screen of my smartphone. For example, I can make a filter "tasks starting today, priority yellow or higher, lists "personal" or "projects", sorr by due date). And make corresponding widget.
Samsung OneUI has widget carousel feature, so I make multiple widgets with different filters and switch by swiping. Very convinent.
Also tasks.org support syncing to nextcloud, but I keep it disabled due to tons of bugs in nextcloud itself.
I make separate list for everything not important at current period of my life, so I can review it later (usually once a week or once a month, my life is very unstable and unpredictable to tell more exactly)
I use this for about a year, so it's not so well tested workflow, but for now it works better than other variants I tried.
