I've noticed strange behavior of Downloaded Files Tab. First: files sorting is weired - not alphabetical, not date/time, not file type - random, but always the same. Second: built-in filters such Documents, Music etc. didn't find anything, while these type of files are just downloaded and are present in the Download folder. Third: searchbox didn't find anything. Fourth: long time of opening Downloaded Files tab.
