Quantum leap of improvement since last alpha release, but a lot room for improvement. a nice basic feature i'd like to request is "save as" option. What if I completed a mosaic, but decided to try a version with additional image source? This is a cpu intensive program (which i don't blame), and building a new mosaic will take awhile. Another thing is, If I try to build two different mosaics at the same time, it crashes and on some occasion while i'm using it alone(I'll send you my log) so therefore, i have to rely on save every 1 minute option, which forces me to slow down the application. Also what happened to "original and mosaic comparision" side-by-side viewing? Also i know this will make the program even slower, but i'd like an option for tile resolution... it maybe too much to ask, but I have to comment that for professionals, the tiles don't look good when i zoom in. I'll give in to leave my computer render for 6 hours if such option as having a 500mb final mosaic image file, is available.

On the bright side, I love the new ability to reuse an image on different tiles and its options, and iphoto source addition. Look forward first Gold Master Stage.
