Awesome!
I've used CLZ Music for around 10 years, and it's been excellent. It's adaptable to my needs, fast, and looks great. Support response is almost instant and they always take the time to explain things clearly.

Our web-based software has been around since 2009, first called “Connect”, but renamed in Oct 2024 to simply “CLZ Web”. The Web software is currently the most popular solution for use on your computer, far exceeding the number of users of the legacy “Collector” desktop software.

However, through the years, there is one particular piece of feedback we kept receiving from both new users *and* from users who switched from the desktop software, but phrased in different ways:

“It is all so BIG!” or “I can’t fit a lot of items on my screen”

And they’re right. CLZ Web has been designed to be “big and bold”, as is common with web-based software. Large fonts, big buttons, etc… It looks nice, but the side effect can be that you can fit less collectibles in your on-screen list. Especially when:

  • Using a low-res laptop screen
  • Using a tablet device
  • Using several layers of toolbars in your browser

To resolve this, we were initially planning to introduce an optional “Compact View” or “Compact Skin”.
But when we starting working on that, we liked the results so much that we decided to make it THE new look of CLZ Web for everyone. It looks so much better, more compact, more items on screen. But never too small to read.

Here’s what we did:

  • New font style to fit the new CLZ styling
  • Slightly smaller fonts everywhere
  • In the main screen, we combined toolbars and made them “lower” overall
  • Lower list rows in List View, by slightly reducing the spacing
  • Reduced the height and width of all input boxes in the Edit screens
  • Reduced the height of the screen titles of all popup screen
  • Reduced the height of the collection tabs at the bottom

This new compact look is going live for CLZ Web within a few weeks. But today, I can share more sneak preview screenshots of the most important screens, with a nice BEFORE (left) and AFTER (right) comparison. Enjoy!

As announced earlier, a big update is coming for both the mobile and web editions of CLZ Games, in which we will introduce the ability to catalog your “toys to life” figures. That is:

  • amiibo
  • Skylanders
  • Disney Infinity
  • Lego Dimensions
  • Starlink
  • Rumble U
  • UB Funkeys

Today, we can finally show you the first sneak preview screenshots of the CLZ Games 10.0 mobile app!
