Inline system file editing (via fileupload widget) #667
Description
Even though it may not be particularly useful by itself, inline editing while uploading files using fileupload widget opens new options like assigning additional attributes without doing the click to open the edit popup. This can be useful when you need to upload tens of files and want to quickly edit their attributes while seeing them all in the list, which is a way to avoid mistakes with large uploads (quick table-like overview of files and attributes without a need to open a popup).
