At work I use outlook tasks with some custom integer fields to prioritise work. Everything is basically numbered to get higher priority things up the list and more visible but I also use the due date and reminder time to organise what needs to be done when (some high priority things need to wait on external input so while they are still my focus I won’t look back at them til the reminder day). I don’t really need to plan time on my work tasks but if I did I’d probably add another column that added a scale estimate, I probably wouldn’t use a specific time period but more use the old scrum method of scaling tasks. Sadly I think outlook tasks is going to be discontinued soon and migrated to the inferior Microsoft planner. When that happens I guess Ill either move to excel or my home method.
For home stuff I build ToDo lists in Obsidian and share that across devices using mega. I’ll generally have a few ToDos depending on context. That is I’ll have a long term one for big things I want to do but then will also build ones focused on more specific things like housework that needs to be done that day or things I need to do for my ongoing house renovation. If the list is for something complex I might build it at high level and then expand our a given section when it gets closer to working on that task. I also use Obsidian for weekly meal planning and shopping lists.
Could also just setup a bootable Linux USB and run his system from that
