Option to keep sort local

[xopo]

If I am inside a folder, and I want to see sizes for all content, I can do that by pressing , and s. Doing this will remain as default and when navigating inside or outside the experience will be sluggish as it will try to calculate size for all folders, some will require permission.

It would be nice to have a setting for sort
[sort]
level = [all, local, local and children]
all - the current behaviour , keeps on sorting wherever you go
local - just for this folder, and ignore when going up or down
local and children - it could make sense to be able to check sizes for this folder children as well
