Short of saving myself a bit of work when tagging, and for custom renaming, I haven't used title formatting since installing foobar2000. If dragging .dlls into a folder is too hard for component installation, my sympathies. I don't know what else is "difficult" about foobar2000.

As for components, the wiki tends to be kept up pretty well. It points to a lot of them. I don't use many anyhow, and don't tend to update them all that often. I don't get any crashes for them, don't lack any functionality...

The people who complain that foobar2000 is too hard are mostly Panels people, and Panels is atrociously difficult due to its severe abuse of title formatting. Many, many rants have been written about how bad Panels is in that regard.

Regarding drag-and-drop configuration of the default UI, your position smacks of someone who has no idea about how to implement such a feature. The current UI design implementation is powerful, complete, and fast. Implementing it using drag-and-drop would be horrendously buggy and non-standard, not to mention the insane degree of programming difficulty, and it would not speed configuration up at all. In fact, it would probably make it slower for most users.
