Very nice tool indeed, funny how the world works. I'm writing an Electron/React/PouchDB application that works kinda like this called "Filebase", you create a library and name it like "pictures", you pick a directory / or single file on your PC and it scans/indexes it, this allows you to tag individual files and folders so you remember what's in it (you can search these tags). you can search and filter by type. The last feature will be archiving but keeping the directory info handy so you can search for items that are archived. I came up with this idea after watching my partner try and organize Cricket art and PDF's. I realized that Windows Explorer kinda sucked for organizing. I wanted to build something that did not modify or touch files itself. It's been a great way to learn Electron. I have to say Electron makes building UI's easy for applications.
