We have hundreds of on-going shared reviews in Tracker. It is very difficult to locate files. The default sorting method appears to be based on recently opened files. If there's a file that hasn't been looked at for months (typical), searching through the "Joined" files is more than tedious. Sorting by file name (as well as other options) would be great. Alternatively, a search function would work as well.

And while you're at it--any way to speed up Tracker on start up? With this many files, it takes a heck of a long time to load.
