I have added a new path to PD, where I have my patches and I save the preferences and close PD. And when I open PD again, the preferences seems to be saved, but the path is not available in the browser. As said I am still pretty new to PD, and this is how I did it in 0.47 version and it worked there
Thanks for the report.
This was slightly broken and I believe it's fixed now, just not in a test release yet. If you want to try, you can copy the update to the helpbrowser GUI script wit the following steps:
1. close Pd
2. right click on the Pd.app (probably in /Applications) & choose "Open package contents"
3. navigate to Contents / Resources / tcl
5. save the file, open Pd & test
