Especially when we do sorting by files/directory modification date by descending.
If the modification of the directory is older than the files inside of it, it should be prioritized lower.
So i can't really find the proper top newer modification files that has been just updated, because the newer updated files are inside the directory which has modification date older.
The current sorting method is not logically wrong either, since we are sorting what is currently viewable.
But if you can have an options to sort by the newest modification date by ignoring the directory, that would be superb!
Sorry for my bad english, i try to explain as clear as possible, hope that's understandable enough.
