dont know if i have already post something similar, but it already floats around in my head for quite some time now (its more a modding toolkit topic, but there is no dedicated thread to the toolkit and it also has links to the gm tools):
a "modding toolkit lite" would be cool. ie a combination of the easy-to-use gm mode and some limited magic of the toolkit. so, like a dummy mode for the toolkit with only limited options activated so that you can quick build landscapes (or maybe even an automatic map builder, which you only feed some parameters like biome, % of water, rock, woods etc.), put in some premade buildings, some npcs, loot, enemies, write a story arc and dialogs, maybe some vignettes and/or an overland map to link several locations and done.
this could of course also be used for quickbuilding gm adventures
