My ideal long-form client:

- Immersive, full screen visual focus
- Focuses on reading, writing, commenting and subscriptions (not so much zaps, though zap button can be there)
- Encourages others to get started
- Focused publishing mode with in-line markup, media inserts, notes inserts or any other type of nostr events (no markdown, at least initially)
- Unsplash integration, upload images, choose heading color if no image
- Basic proofreading / grammar handling built in
- Ability to subscribe to posts (free tier, just to get notified when a new post is published - maybe via DM). 
- Ability to subscribe to author - both CC and sats
- Just works - no need to learn about relays or keys the moment you start (you can learn about keys later)
- Constantly fresh - every time you open it, you see something new
- Looks and works super good on mobile
- Consistent styling, branding, good UX with transitions
