Maintainence only

I midspace have stopped working on Space Engineers related stuff. I will only be fixing issues that cause SEToolbox to crash. I won't be adding or enhancing any further features. There is a lengthy post here on the Keen forums about this decision. I'm open to other developers taking over, or at least contributing further to SEToolbox.

You can’t perform that action at this time.
