Releasing the Bloom beta later on today. Bloom is a super simple and intuitive file manager for Bloom and NIP-96 servers. There are similar things around like Blossom and Bouquet but it looks like they haven't been worked on in a while and there were some UI things I wanted to tailor to my tastes.

Bloom does support server sync and makes every attempt to sync blobs across servers either via mirror where supported or direct upload if not. There's still some quirks with syncing and I've only tested it across a couple servers, but it should be pretty self-explanatory and simple to use.
