Tools - Scenario Editors
The scenario editors are most likely the editors that most people are waiting for. As of yet, not a single editor has been completed. The scenario editors allow you to alter pretty much everything in the game missions, and all functions should be working graphically, so one can completely forget about these highly annoying coordinates.
Krom's Scenario Editor
After being on hold for quite sometime, it seems like Krom has resumed his work on creating a scenario editor. Current builds of his terrain editor already allow placing of buildings and roads graphically, so I'd say we're definitely getting to the point when all map editing can be done with one and only one single tool! :)
