MainViewModel.Overlays.cs (194 lines) takes the settings/bug/feature/about panels + creator-hub links: panel state (IsSettingsOpen/IsBugOpen/IsFeatureOpen/ IsAboutOpen via SetPanel, IsLicensesOpen, IsAnyOverlayOpen, OverlayTitle), ShowOverlay/ShowLicenses, bug/feature report fields + SubmitBug/SubmitFeature/ ComposeEmail/OpenUrl, the About-hub consts (ChannelUrl/MastodonUrl/CoffeeUrl/ PremiumUrl/IsPremiumAvailable), SupportEmail/AppVersionLabel, LicensesText, and the overlay command declarations (OpenSettingsCommand..OpenLicensesCommand). Core drops 940 -> 758 lines. Ctor command assignments and all other wiring stay in core; SetPanel/ShowOverlay keep their cross-partial calls. This completes Phase 1: MainViewModel.cs has been split into 10 functional partials (1,890 -> 758 lines in core). Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures. Docs: index.md Overlays row added, About-hub row re-pointed, tracker marked Phase 1 complete in the same commit.
ytLlive
A creator-proof live-streaming and recording app for YouTube — native Windows (C# / WPF / .NET 8).
Screenshot
Design Principle
This software is so intuitive that even the most right-brained person can easily intuit and use it.
Every feature is measured against this. One-click go-live, sane YouTube defaults, visual scene building, and no dead ends — every action has a visible outcome.
Why ytLlive
OBS treats YouTube as an afterthought; SLOBS is Twitch-first with YouTube bolted on. ytLlive is designed and dedicated to YouTube livestreaming and recording, and to YouTube's specific quirks.
Account Assumption
ytLlive assumes you already have a YouTube creator account — connecting uses "Sign in with Google" to link that existing account. ytLlive does not create accounts. If you don't have a YouTube channel yet, set one up on YouTube first, then connect it here.
Run
