It would be interesting to get more details about a single file when clicking on file name. The same details as in standard amule would be interesting, but at least, the complete file name is mandatory. In the current version, if two (or more) files share about the same first 40 chars, it is not possible to distinguish between.
Clicking on filename would show full details (url, comments on file, last complete seen date and so on), clicking on number of sources would show detailed list of sources and ranks in credit queues, clicking on priority would switch between (auto, low, medium, high) and the two arrow button would be removed.
