NinjaPanel and LDB

[Spectro]

Years ago I used Titan Panel. I discovered Fubar later on, and liked it better. I haven't really needed any kind of panel, but I decided to look into fubar again. I came across NinjaPanel and LDB. I guess I don't fully understand what each addon does. LDB is the base for the LDB plugins, but you need a display addon like NinjaPanel, correct?

I guess I got a little confused when people said you can use Fubar for LDB when I thought Fubar was its own addon with its own plugins.

I know this is more of a LDB question in general, but I couldn't find a forum for LDB and I was interested in NinjaPanel anyway.
