Great decision.
Perhaps it would be a good option to separate into two classes, one with links to "Precompressors / Compressors" (like XTool) and the other links to graphical user interfaces (GUI) that use multiple compressors (Most of the current list of Compressors).
I think this one was missing:
Windows Phone Installer (bug free), and if possible also link beside separating by "/" the version with DiskSpan GUI support:
Windows Phone Installer (DiskSpan GUI)
There are also these versions here that can be placed side by side:
BlackBox UltraARC Support /
Black Box DSG (BBS DSG)
