Nothing but praise
I love the app so far. It's a movie collectors dream. I've been wanting to make a list of my movies like forever & this app makes it dimple to do. I have almost 500 movies on your app & still learning everything about it.
Love the fact you can back it up on the cloud so you never loose it. Wish I found this app sooner or had the technology to do it years & years ago.

I'm having so much fun with your software!!
I am so overwhelmed and excited about this app! I have also installed your music app and will install your book app next. What a time saver!!
I was going to create all this on Excel - whew, that was a huge project before me. You saved a huge amount of time for me.
Your app is so user friendly. I just experimented and very quickly I was up and running. I'm telling everyone I know about these wonderful apps!

Three weeks ago, we did a huge “more compact design” update. Today, we are continuing with another update that improves the design, layout and performance of your album details panel.

Here’s what has changed:

  • Flexible layout: the layout now fully adapts to the width of your details panel.
  • Fields moved: we moved some fields around, to make sure the most important fields are at the top.
  • Faster loading: the details panel now loads much faster, as it now delays the loading of the backdrop.

  • Faster loading: the details panel now loads much faster, as it now delays the loading of the backdrop and because the trailer video is not embedded anymore
