Well, digiKam is making great strides towards being a great digital image organiser and editor.  Not to say that it isn’t great already of course :)  However, Gilles has recently introduced what amounts to full MRW support (and other RAW formats) by switching one of the underlying libraries to the Exiv2 project, and then contributing an MRW parser to the Exiv2 project.  This means I can do everything inside of digiKam from offloading the images (which I do via a CF reader to save camera battery), to tagging the ones I want (and digiKam can write the tags as keywords in the metadata), tuning the raw file and saving for web publishing as a JPG or PNG.  I still use JPG for size reasons, and the fact that PNG metadata writing doesn’t seem to be complete yet.

There are a few things I’d still like to see in digiKam, and while I don’t have time to code them, I can at least file requests with full supporting reasons :)
