Thank you very much for your question!
You may group tasks in lists, manually sort tasks under Next, you may also use the combination of 'Group by' and 'sort by' in filter (advanced search), which can be set in web version - Search - Advanced Search - Save as a Filter, and can be viewed on any platform.
Could you please tell us your exact needs or give me an example so that we may better help you?
Have a nice day!

For example, I can't sort by Start time and Priority my Next list when I group by Context when I want to take a decision about what is really my next task to do.

I'll open another suggestion about to include duration as an sortable item. And to aggregate Energy.
Context, Duration, Energy and Priority should be criteria to do a next action.

@Gamgster Thank you very much!
If you group by Context, the tasks in the list are automatically sorted first by Priority and then by Start Time, so you can easily pick the highest prioritized task since it is the first highlighted one in the list with dark orange line at left.
As to putting the duration (Estimated time) as an sortable item, we've still been thinking of solution. Energy would not be considered for the present.
Thank you!
If any problems or ideas, please feel free to tell us.

The problem is I can't set another combined order to sort in a filter.

@Gamgster Thank you very much for your question!
Do you mean it's not enough for you to have both Group by criteria and Sort by criteria in a filter? You need more combined sorting? But that may makes things too complex.
