The latest build of the US$145 FotoStation 4 for Mac and Windows, Build 80, adds keyboard shortcuts for thumbnail rotation among many improvements. D1 discussion list members should note that if you received Build 80 via email last week from Fotoware directly, the Build 80 available from the website fixes a crashing problem on startup and modifies the thumbnail reading logic in the Mac version.
FotoStation 4 is available as a 15 day trial, and can either be purchased directly from Fotoware's website or from numerous pro dealers.
