Well there are a few things they should do:
First of all a simple grayscale heightmap importer for terrains. Last time around I had to write it myself and it never took of. I'm not even sure at the moment it still compiles.
https://github.com/Celludriel/DOS_Terrain_Importerhttps://github.com/Celludriel/DOS_Terrain_Libhttps://github.com/Celludriel/LsLibhttps://github.com/Celludriel/DosPakI do not want to go through this again. While I like programming, figuring out the files was living hell of try and error. Finding out which Endianness that had been used etc... it was just a nightmare. I don't think anybody ever used my tools either which was a big letdown as well. So in short:
- Open file descriptors so modders can write editors for them
- Greyscale heightmap importer so a lot of the sculpting of the terrain can be done upfront
- Easy dialog editor so storytelling can be done quickly and you aren't fighting the tools and are focusing on the story
- Easy templating of items so it doesn't take hours to make a new item
- Scripting language for creating events would be nice (like in NWN) but I can understand this won't be in it
