Andy over at DAMroundup has created a great new video review of Idimager version 5. Check it out
http://www.damroundup.com/idi5/. Keep in mind Andy has enabled auto-syncing which runs asynchronously but can still slow down the application during syncing. I do not do that so it is more responsive. He also talks about recipes which is a really nice feature. I use it on my DNG's and JPEG originals to create nice frames, border effects, captions, vignetting, etc. without having to create derivatives.
