[Feature Request] Edit more fields in the Exif

[gymnae]

Hi @pulsejet ,
great tool, seems much more mature than the current Photos app, might even replace photoprism.

Feature request:
Being able to adjust caption/description in Exif data

Reason:
Other tools, such as photoprism, can read the exif caption/description metadata to display context of images. I'd be great to be able to add such metadata in memories directly and potentially show this data when displaying images in thew viewer

[pulsejet]

Can you provide an example of such along with a list of metadata tags? I want to make sure we have compat with other photo libraries.

[gymnae]

I added caption, title, rating, and a label to this photo via Lightroom, they show up in Nextcloud and preview.app:

This is the full amount of metadata embedded as EXIF/IPTC metadata. I marked the ones that are of interest to me. I noticed that Caption and title appear twice, while I added them only once.
