If you're already at a desktop, you have a browser and a text editor — the app exists for when you don't. There's no web version of the editor planned. The developer tools bundled inside the app are a better fit for the browser, and those are being built as free web tools here.
My project files disappeared
Open Version history from the editor menu — the last 10 saves of any file can be restored. Auto-save also keeps a recovery copy if the app closed unexpectedly.
GitHub sync isn't connecting
GitHub requires a personal access token rather than your password. Generate one in your GitHub settings under Developer settings → Personal access tokens, with repo scope enabled.
The preview looks different from a desktop browser
Preview runs in Android's WebView, which is Chrome-based but can lag behind desktop Chrome on newer CSS features. The device emulator bar helps check layout, but test on a desktop browser before publishing.
