Show HN: FeatureFlags.app – Feature Management for .NET

Feature flags are common these days, and the .NET feature management library provides a lot of the plumbing to make them easy to get started with. The missing piece is a UI for managing flags - unless you are using Azure App Configuration. Relying on `appSettings.json` gets awkward when non-technical users need to change flags, deploys are slow, or the application is running in a distributed environment.

I built FeatureFlags.app to fill that gap - a simple UI for managing .NET feature flags that doesn't require Azure App Configuration. It's still early, so I'd love feedback from anyone who has dealt with feature flags in .NET.
