This is a small feature request, but it would be nice if World Machine files had a file thumbnail/icon to help identify them faster and if World Machine associated the files with itself it would be great to just double click on a TMD file and open up World Machine.
It would also be helpful to have a button that terminates the build, but saves the state of the devices that are already built. This would be useful for when someone is building a lot of nodes and they want to only build halfway, but is building the entire project. This would save a lot of time in many use cases.
