I don’t have a UI, just an idea. I wanted to make a tagging system that doesn’t embed tags if you later change how you wanted to organize images. You start by loading a image and typing a tag. You then save your tag. You can then use the search field to search said tag or tags.
With that if you have four the items come back as a 2x2. If you have even more come back you get a forward and back button to sift through the 2x2s. The last bit I added was if you click the preview it opens the image from your drive.
