missing thumbnail-Sort-Buttons in theme i-feel-dirty

[EdeWolf]

Hi there,
currently i'm using the very popular theme "i-feel-dirty" and i like it, but
if i want to change the order of the overview of thumbnails i first have to
switch to another theme where sort-buttons appear above the album,
and back again.
The sort-button obviously are not implementet in that theme.
Has somebody already completed the theme with the sort-buttons?
-or can somebody tell me how to do that? ... please! 
thanks,
regards
Ed

That feature has probably been removed intentionally, as it's not just the buttons but also the corresponding labels which don't show up. I hadn't looked at the theme's code yet.
