This is CLZ Alwin, with the newsletter for May 2025.

Obviously, the big news for this month is the HUGE update for all 5 flavors of the CLZ Web web-based software, dramatically improving the look and usability.
A more compact design and layout to help you fit more collection data on screen.

The first feedback from users has already arrived. Some examples:
“SO MUCH BETTER!!”, “I like it”, “It works a treat…..”, “The new updates are phenomenal.”, “FANTASTIC!! Thank You”, “The whole application looks more refined now. Thanx for the great job.”, “you all continue to surprise and impress me year after year” and finally…

“Just wanted you to know that i love the new visual redesign of the Web app(s).
It just flows better, i get more info on less area. Impressive work, and still it feels like it always has, just better.”

Thanks all for the praise! As is to be expected, the new design came with some bugs and annoyances too, which we fixed right away. (hint: since today, the Add button is back on the toolbar 🙂 ).
Full details about the CLZ Web re-design below.

Of course, the other big project at the “distributed CLZ HQ” (yes, we’re all working remotely), is the addition of Toys-to-Life support in CLZ Games (both web and mobile).
This one is taking a bit longer than expected, but… it’s very close now. We are planning to go live with the Web edition next week, with the mobile app following a week later.

Finally… I am happy to announce that we have hired a new web-developer, Michiel. Which means we can make even faster progress on the Web editions and other server side projects.
Michiel’s first project: a big update for CLZ Music, with many new data fields!

The topics today:

  • CLZ Web: More compact design and layout: fit more collectibles on screen
  • Very close now: the new CLZ Games, with NFC scanning for amiibo!
  • Coming up: CLZ Music 10.0 with extra data fields

Coming up soon: CLZ Games 10.0, with support for cataloging amiibo, Skylanders, Disney Infinity, etc…

For amiibo (and possibly Skylanders on Android only), we are introducing a super cool new way to add your figures:
Just scan their NFC with your phone!

Check out the Sneak Preview video below:


It’s that time of the week again…NCBD!

History will never be the same!: Giant-Size X-Men #1. Ever since she discovered she was a mutant, Kamala Khan has been balancing her previous life as Ms. Marvel with her role as a leader in the new community, but her conflicted identity has come at a deep personal cost. Now, pulled into the distant past by an unhinged villain with deep ties to mutant history, Ms. Marvel will witness the iconic birth of the Uncanny X-Men and their first encounter with Krakoa from an all-new, all-different perspective. But when history begins to change… can either Kamala Khan or the X-Men themselves survive the experience?

England, 1349. Sir Hugh de Grey, the Pale Knight, returns from war to find a land ravaged by the Black Death, and his son dying of the plague. When he prays to God to save his son’s life, it is not God who answers, but Death himself. And Death is willing to cut a deal.The Pale Knight #1 Written by Peter Milligan and art by Val Rodrigues & Cris Peter.

As My Mothers Made Me, Part 1: Absolute Wonder Woman #8
The Tetracide was a much greater threat than Wonder Woman had imagined for her first battle on the surface, but The Tetracide was child’s play compared to negotiating the complexities and evils of man’s world. The mysterious Area 41 and its Black Box Maze will be Diana’s greatest test yet… and what she finds inside will shock you!
