Add open with..
The open with should or could allow a person to associate a file type like a .log to be edited with a installed text editor like a windows pc can.
Need ability to select any other applications installed to open with.
Then you can really call yourself "better open with"
This is a must add to really make a difference between a ok and a GREAT application.
This could be a menu that will allow you add custom file extension manually and choose open with from that same menu. Also a long press on a email attachment or file in a folder could be associated instantly.
