I’d like to give you a suggestion to improve this great Painel.
There is some duplicated information like the column Extension since you can see it in the Filename column.
There is a not so adequated information for this kind of section like the column File Comment. It could be available only when you select the file.
For replacing these two information data I suggest you include the Total Number of Views and The Total of Replies related to each file posted.
It is just a suggestion.
