Questions for szurubooru TagsResearch entry

[Qronikarz]

Hello.
I am the creator of QuoMediaView and TagsResearch which both deal with tagging images, media and other things. Szurubooru is one of the programs I have included in TagsResearch and I want to complete it's entry in full.

I figured I can just ask here about few things that I didn't discover from the readme and documentation.

1. Does it have updates beside the release ones? The last v2.5 was released in 2021, but GitHub has activity from time to time so I need to know if it gets updated still to properly classify it.
2. On which of the architectures does it currently work? 32 bit, 64 bit, ARM 32 bit, ARM 64 bit?
3. Does it have dark mode?
4. Are the tags stored in SQL database or some other form of tag storing is used?
5. Readme mentions "Tag suggestions". Does that mean there is some form of AI object detection used?
6. Can tags be exported/imported for backup?
