The scraper was improved under helix.Really? Without nfos? Nice. I should edit my post to say XBMC on that part. I only let Kodi scrape my movies library without nfos so far. I have noticed the scraper is faster, good news all around.
I have a c2d machine with helix and my other machine still runs Gotham. I feel helix still is faster on the c2d machine but could be placebo for all I know.
I also run everything through filebot where before I didn't but I feel it's only gotten more polished of an experience.
All these media center apps will only improve more now that they're hitting mainstream and much more effort is being placed on getting them integrated. I'm hoping that netflix/Amazon prime etc work with people for integrating into their application. I'd like to see them integrate with plex. Preferably with Kodi but I doubt it'll happen.
