Transfer Window tells you when to leave for another planet or moon, and what it'll cost.
Pick a destination (or just target a body) and the window shows:
Then Create node places the ejection burn for you, and Warp to window takes you there.
It also works for moons, returns from a moon to its planet, and from the launchpad, using a parking orbit for the departure figures. The window matches the stock UI, can be moved and resized, and is translated into German, French, Spanish, Brazilian Portuguese, Russian, Japanese and Simplified Chinese.
Figures assume roughly circular orbits in the same plane, so eccentric or inclined targets like Moho and Eeloo need fine-tuning.
