While browsing around kde-look.org, I’ve stumbled upon a nice little Plasma scripted widget, and I’m publishing this to have it get more exposure. A good part of the KDE community knows at least little about Nepomuk, and its ability to attach semantic tags to your files - basically words that describe the file, be it an image, a text document, or anything you’d like. For example, you could tag all the photos from your vacation with the name of the place you’ve been.
