I'm currently building an app which I hope will allow batch exporting of HISE projects, auto notarization on Mac, and auto-generating installers. So far I have the basics working on GNUx. I need to finish the interface and add the batch handling, but that shouldn't be too difficult, then I'll tackle the other platforms.
This app should make it much easier for everyone (and especially beginners) to export their projects from HISE and build installers.
This is what it looks like so far (it's an ugly work in progress).
