@natinusala Please could you add the following to each of your OS entries for better support in PINN: ``` "url": "http://www.lakka.tv/", "group": "Games", "supports_backup" : true, "download_size": XXXXX, ``` Where...

@natinusala - Thanks for adding the extra fields for PINN. Could they be added to the entries in `os_list_v3.json` too? (In fact, the download_size entry only makes sense in `os_list_v3.json`...
