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!

Further tweaks to eBay links

Jul 24, 2025

Two weeks ago, we introduced the new “Automatic eBay search links” in your CLZ Web software. After launch, we received quite a bit of feedback about this feature, both positive and… let me say… less positive 🙂

So we sat down, went over all feedback, and then came up with some tweaks to make everyone happy!

First, I have to repeat: this feature is OPTIONAL.
Most users love having the quick and easy access to eBay listings for their collectibles, either to:

  • easily get a feel for an item’s value, by finding its Completed/Sold listings on eBay.
  • easily find available copies on eBay, useful for your wish list items.

However, if you don’t see the value in this, if you don’t find this useful, then you can easily DISABLE this feature in the CLZ Web’s Settings screen, on the bottom right, under “eBay search links”.

New:

  • “Update from Core” will now replace preview art with final cover art if it is available.

Some explanation on the above:
If no regular art is available yet, comics often will have preview art as front cover. Once final cover art is available, we update the comic in Core with that final cover art.
To get the final cover art, just select one or more comics, then tap Update from Core from the action menu.
