Currently, the "descending" option to sort the file list is placed within the action bar menu as following:

We can improve this behaviour in two different ways:
Sort descending , so only the word Descending can be confusing

@cdamken @voroyam @lefherz @pmaier1 what do you think?
The more options to sort the files the better, imo.
@voroyam The question is: Where to show the "Descending" menu item?

In the sort dialog. BTW, "smallest - largest" makes more sense to me than "smallest - biggest". Files are large, not big.

true.

I've tried that at the beginning, however it's not quite trivial to put it there since that menu only accepts either radio buttons or checkbox buttons, but not both. Supporting both would require to create a new layout.
Could you be convinced to something like that:


I would choose the second approach
First approach overloads the menu. The menu is intended to be a list of available options and there are mixed checkbuttons, radiobuttons and other options, not a good UX from my POV. Second option is better so the main menu structure remains and it is clear in the sort view the available options.
here is an implementation of the second suggestion: https://github.com/owncloud/android/pull/2226
idea - what if we leave out the descending option, and instead make it descending, when people tap on "A-Z" the second time, even if it's already chosen? so if "A-Z" is checked right now, user taps on "A-Z", the option morphs to "Z-A"? then we could get rid of the ugly descending checkbox.
Well but the checkbox can be combined with all the other options. If we really wanted to replace it we had to add 3 more options. @lefherz why do you think this solution is ugly?
we can create a separate issue to be scheduled with this enhancement. It does not have room for 2.8.0 (current milestone)
