Would be useful to open the files inside torrents from within tTorrent interface.
There are 2 options:
1) Torrent menu => "Explore torrent folder"; this could be performed either in internal file explorer or a system default one. The action could even use the icon of "Browse for files" action so it's a 5-min job to implement. Not a very important feature though.
2) Torrent files list => "Open file" on double-tap (or some other trigger); pops up a system dialog to choose an app to perform opening. This feature seem much more useful.
