Before my "Bridge or better" statement, I wrote "I need to be able to view thumbnails of every image type, from RAW to raster to vector." Not vague at all about that. I would like to explore replacing Bridge as an image browser. That's what Bridge does.
It would be great if the replacement:
1. Could browse every image file type as a thumbnail, plus open any other file type with a double-click.
2. Could index/cache a large folder faster than Bridge. Bridge takes several minutes to index a folder with say, 2000 images. For a wedding photographer or an air show photographer, 2000 images isn't that much.
3. Customizable viewing of basic metadata such as file size, image resolution, etc. without opening a metadata panel.
4. Had a pleasing user interface. The default UI for Bridge isn't that great, but you can customize it to have a similar color scheme to the default UI for Affinity. Some of the other image browsers I've looked at are just butt ugly. It's hard to get in the mood of making something beautiful when you're looking at a 1990s-era UI.
