I’m working on a small project for Kerbal Space Program.
The goal is to fill in a few gaps left by other mods for my own play style.
Easy changes: KAS and TweakScale config additions for mods that don’t already support them.
Moderate changes: Add functionality to existing parts. (Such as adding a radio to Universal Storage’s EVA-X pack for transmitting science when away from a craft.)
A bit more complicated: Adding new parts, such as the Vernier OmniRCS, which uses the same specs as the stock Vernor engine, but with a bit more flexibility.
See my post on the KSP forums for more until I update this post 🙂
