Do you use a form of some sort to log planetary data or do you just keep notes? I'm thinking of whipping up a sort of Imperial Galactic Registry form that includes all the general info about a world, a picture if I can google one and a basic world map to locate cities, starports, main features etc. Tuck them all in a binder or just keep an electronic file of them handy and expand them to include the locations already detailed in the published stuff. Good idea or just more work when a few notes does the trick.
While Im at it, do any of you actually locate settings on a world map of some sort? Do you care where one city is in relation to another or where the mountains are in relation to the coast during an adventure? Or is this strictly a scenario driven idea?
