Greetings,

Thanks for a helpful upgrade. In testing so far, I have only found one ongoing error and I have only one observation.

Modus Theme CSS errors
The suggested fixes in my Themes post, [Github] piwigo-modus issue #75, have not been applied. I was able to test them on 15.0.0beta1 and found that they still work fine.
The integration with the Smart Pocket theme makes these changes unnecessary for mobile devices but I still want to use Modus in a small portrait window on my desktop. These corrections would also be handy for long term Modus users who have never installed the Smart Pocket option.

Batch Manager enhancements
I have illustrated this with three screenshots, on my Test site. The OpenStreetMap plugin added its details to the old Batch Manager form but they are missing for me on v15. On the third screenshot, I have suggested that the Edit Photo form offers a way round this.
The OSM plugin still adds a predefined filter for "OSM Not geotagged" in the Batch Manager. This makes it a great place to fix this issue, providing the map can be displayed for editing.

Thanks for reading all the way through this!

Best wishes,

Michael High
