Zimaphoto première utilisation

Hello,
I installed the ZimaOS beta on my system specifically for Zima Photos.
I appreciated the option during installation to choose which hard drive would store the photos.
In my case, I had simply copied my photos onto the hard drive in a bunch of folders named after the event date or type (birthday, family meal, etc.).
For now, I’m letting the machine index everything.
One thing I’m missing is a small indicator showing whether or not an action is currently being performed in Zima Photos; I noticed that the photo date doesn’t always match the EXIF ​​data—it often reflects the file copy date instead, which is annoying.
I tested a video shot on my Xiaomi 15; I can hear the audio, but there’s no picture. I haven’t checked other videos yet.
It would be great to be able to specify a preferred viewer on the PC—in my case, FastStone Image Viewer.
I’d also like the ability to neatly reorganize my folders into a single master photo directory; will Zima Photos allow for that?
Identifying duplicates would also be useful, along with the ability to compare them to weed out false positives.
Indeed, I have several years’ worth of data listed under 2026. Thumbnail display is slow. Will Zima Photos generate thumbnails like Immich does?
The program doesn’t allow you to delete a photo either; I would like to be able to change the date and name, and fix red-eye.
After an hour, I found the indexing process stuck at 100 images; the program says “Running,” but I don’t see any movement. It’s still showing 100 images out of 31,000.
The system consists of an Intel G4560, 16GB of DDR4-2400 RAM, a Crucial BX500 SSD, and two 2TB Seagate Barracuda Green hard drives. I don’t have a graphics card with 6GB of RAM, though I could install a GTX 1030 2GB GDDR5—but I don’t think that would help.
Thanks.
