Shortcuts for sorting topics

a) I miss a keyboard shortcut to apply the last used subtopic sorting directly.

b) Interactive symbol groups such as Priorities and Progress, but also user-defined symbol groups of a similar nature, should perhaps have an additional option. For example, if you right-click on a priority icon, the sort option should also be on the menu. It would sort the topics on the same level as the right clicked object.

c) Sorting options should be saved and automatically appended to the sorting button as a drop-down list. The sorting tool would not have to be operated again for each known sorting type that has long been set. That would be much easier, more spontaneous and would save time.
