I had an idea for a new linux file manager. At the moment I'm mostly happy using nnn, but there are a handful of things that could be improved.

Having the filemanager be graphical, but still fast and designed for experienced users like nnn would allow for displaying image previews which is the biggest thing I'm missing with nnn.

The second improvement is to do with hardlinks. Eventually, I wish to create my own operating system based on tables instead of files to seamlessly allow your media to be tagged and effectively represented in many different collections at the same time. Rather than a file being limited to a single folder or concept. On linux, a filemanager could actually use hardlinks to emulate this concept quite well.

The idea is if you have a folder called "pictures" containing the folders "climbing" and "2025" ideally I should be able to put my climbing photos from 2025 into both of these folders.

The filemanager should do two things to make this easier: display a list of "tags" which are just alternate locations the file is hardlinked. For this example a climbing photo in the 2025 folder would show the climbing tag. Additionally, it should make it easy to "add tags" and autocomplete a list of sibling directories.
