Goodweather, if you need somewhere to host it long term (or even until the issue is resolved here), please let me know via PM. You could supply a link to the file similar to what I did with the PC3 panel.
I am using Google Drive. Very reliable and lots of space for free. When you would publish a panel “the way it was meant” you would make instances for standalone/vst/au for every OS (Mac, Win, Linux). Instances are quite big. Mac instances for example are several dozens of mb’s. I still haven’t found the time to make instances out of my panels. I had big problems with the savestate feature. Working well with .bpanelz but being unpredictable with .exe and other instances.
