What exactly would you like to be improved?
I can login by public-key and I see a lot of things that I'm not supposed to see https://image.nostr.build/31a55a9ca5602820d6851b33c2c8cbce9e9f6cee7491e755aef15ac4df8b17a6.jpg https://image.nostr.build/f34b6fd6edf35e729ca6947233e878dad77ec71797e2ca1631968f2f764d1a3a.jpg https://image.nostr.build/b378a37c24d71145c73ba1be3dd4910a307d81d766e5b58e35fc92d7afd9c04f.jpg https://image.nostr.build/cc6b01243e44ab1022538a7dca5293d5e0dd63f5ad6f612f9b3b85b0f03241fb.jpg
