A very happy customer
This cataloguing database is absolutely fantastic. I wasn't sure at first but I had the 7 day free trial after day two I knew it was absolutely worth every penny of the £17.50 a year subscription.
In fact I am so impressed I will be buying the music cataloguing software as well. Keep up the great work absolutely fantastic.

v10.1.4: Fixes for “edge-to-edge” issues

Feb 12, 2025

The last update where we introduced edge-to-edge support for Android 15 and higher had a couple of problems that we’ve now addressed in today’s new version.

Fixed:

  • Some parts of the screen could be blocked by Android navigation bar:
    • Collection tab-bar on startup
    • All/Action buttons (when selecting series in the main screen)
    • Add button when checkboxing multiple issues to add

Today’s update is all about improvements to the screens for dealing with “unrecognized barcodes”. The main thing being the new option to report unrecognized barcodes for movie box sets (and which movies are in them!).

Welcome to this weeks edition of New Comic Book Day.

Let’s kick off strong with everyone’s favorite antagonists! In Star Wars: Legacy of Vader #1, published by Marvel Comics, comic giants Charles Soule and Luke Ross join forces and take a deep dive into the obsession Kylo Ren has with Darth Vader. I find your lack of faith disturbing if you’re not totally looking forward to this new ongoing series!

Dynamite Entertainment’s monstrous and merciless one-shot Savage Tales: Winter 2025 Special has some brutal and exciting stories starring fan favorites like Vampirella, John Carter, Dejah Thoris and Red Sonja. Reading this action-packed comic should give you a ripping good time!

And last but not least Batman, Vol. 3 #157 sees the end of Chip Zdarsky’s exciting run on this series, so prepare for an action-packed final story arc with Batman trying everything to save Gotham City once again!

Happy Reading!
