Handling other types of feed

Thanks for your help with my previous query.

I realise this is a Google calendar app, but I was wondering whether there is any way for it to deal with other common feed types? For example, Facebook uses:

webcal://www.facebook.com/ical/u.php?uid=nnnnnnnnnnnnnnn&key=xxxxxxxxxxxxxxxx

but that will not work in the plugin (the feed URL appears blank). I also tried an edited version:

https://www.facebook.com/ical/u.php?uid=nnnnnnnnnnnnnnn&key=xxxxxxxxxxxxxxxx which loads an .ics when tried in a browser but gives “The feed could not be found (404). Please ensure your feed URL is correct.” through the plugin.

I have managed to get it working by importing it into Google calendar and then linking that calendar into the plugin, but this is reliant on Google refreshing the feed (which it does very infrequently) for up to date events to show.

Not to worry if what I am asking isn’t possible – a possible future feature? Thanks for your help!
