I felt it was difficult to create mods with the current tools, so I created my own editor, built to work for SoaSE Mods.
The project is hosted on BitBucket, here: https://bitbucket.org/jkoritzinsky/soase-mod-editor-core/overview
I will add extensions in the future, and post the links here. To download, just click download and choose which download you want. This application requires .NET 4.0 (or 4.5) to run. It should work on XP, Vista, 7, and 8, but I have not done extensive testing on all platforms.
If there are any developers out there, this application is written in C#/XAML and targets .NET 4.0.
