Spring RTS Engine

I know its not a big thing, but I found it usefull when placing Regions for Mearth Risk on the map:

Move mouse cursor to where you want to place a point, type "/place SomeName", and it will print it to places.lua file, in a format you can easily copy&paste into your lua. It will append new entries to the file, so mark all places you need, and then copy stuff from the file.

There are a couple widgets to let you just place chat points, though it would take a tweak to store the text.
