This is a very simple Kerbal Space Program plugin to display the positions of all planets, moons, and the current vessel after a selected time interval.
It's helpful especially for gravity slingshots, for example not having to "sweep" your node path across the orbit of a Joolian moon in order to find an encounter. You can simply select the time where you would intersect the moon's orbit, and the plugin will show you where the moon actually is.
It's also helpful for visualizing the position of two planets as time progresses, to better plan interplanetary transfers. There are other tools that will do that calculation for you, but this is a more hands-on approach.
