I had just been looking for a windirstat like tool for linux the other day. What I really also want is a way to do an offline index that this reads ... I ended up using duc. Maybe I will fork and add it! thanks for sharing!
no problem!
I had been exploring using an embedded database as an index, but for my current use case, waiting just under a minute to rescan my /nix/store on a weak mini-pc is acceptable.
Also looking to add inotify integration, which would require an index to accurately update the visualization.
