Sort Siblings Once as far as I can see only works on the focused folder, please consider making this a global feature as well ( maybe Sort Siblings Once Global.
Current: If I click inside folder 1 then it will sort A Z B to A B Z.
Suggestion: Click anywhere in the section and it will sort Folder 1 and Folder 2
Folder 1
A
Z
B
Folder 2
C
Y
K
Thank you for the consideration...J
