If you use singletons in your project or Unity's hot-reload is not an option for you, this plugin could help you by automatically relaunching your scene after each compilation.

This tool will automatically relaunch your scene after the script compilation is complete, given the editor is in Play mode when compilation starts.

We originally created this tool to shave valuable seconds from our development process.

Now we don't have to stare at the compile loading indicator and manually relaunch the scene after each script modification.

Verified on Unity v5.4.6 and higher
