Back when KDE 4 came out, it was missing the “send file” option from the left click (service) menu. Pretty silly. You create a desktop environment, and incredible file manager like Dolphin, and then forget to make it so you can pick a file and email it with the official KDE email client…
Fortunately, the fix was pretty easy: as service menu… so I cooked up a pretty simple fix, and posted it on KDE-Apps. The menu allows you to select one or more files, right click, and select actions… send with kmail. Every so often, people suggest improvements and we add them in.
