An official Mozaic user script repository has been established at hosting around 195 scripts (11.01.2021)

To load scripts from

  1. Go to Patchstorage a browser on your iPad/phone.
  2. Pick Mosaic on the main page. Navigate to the desired patch.
  3. Bottom right corner of each patches intro card is a download icon (with the number of times its been downloaded.
  4. Click on it.
  5. If mozaic is installed, choose —> Open in “Mozaic”.
    (The “More” option lets you backup to dropbox or another app/destination.)
  6. On iPadOS 13.x safari downloads all files to 'On My Ipad / Downloads'.
    Use the Files app to open that folder, long tap on the downloaded Mozaic patch
    and choose 'share' and then select 'Open in Mozaic'
  7. The 'Open In' or 'Copy To' action will open the Mozaic standalone app not the AU.
    Press the 'LOAD' button to open the preset browser
    Search for the name of the downloaded script and tap the name to load it.

If the name of the downloaded script does not show up, press 'Refresh' in Mozaics preset browser to update the list.
This also works in AUs that were loaded in a host during the download action.
