We Need A Map Editor...

[LordBT]

We need a new terrain editing DLC, and a map maker DLC, so you can attach a custom made map to what the game gives you. that would be awesome! be able to build another town in a editor, setting up waypoints for map transitions, make new characters for this new town and have custom dialogue, custom shops, custom everything!

You can get mods to do these things or learn how to edit the maps yourself to add in/remove things: http://community.playstarbound.com/threads/modding-guides-and-general-modding-discussion-redux.109131/

As of now, you can do pretty much every you've just mentioned. I doubt CA would go out of his way to make a fresh and new player friendly tool just for the sake of editing.

It does have a bit of a steep learning curve but once you get over that, its easy as ABC.

Or just try out different maps and mods made by other people. Trust me, they are much better than you may think. Some of these mods, man not even CA could've made it better.
