Quick UI (no Command Palette)

You don't have to live in Ctrl/Cmd+Shift+P — every common action has a button, menu or shortcut.

Control Panel: click the SN Widget Kit icon in the Activity Bar (left sidebar) for a panel with connection status, one-click actions (Preview · Debug · Push · Create · Import template · Pull · Snapshot) and toggles for Auto-Sync, Offline mode and High-fidelity artifacts. It also has the Working Context fields: two independent pickers — Application scope and Update set (the Update Set field filters to the selected scope). This is the main UI.
Editor title bar: when you're in a widget file, Open Preview (◐) and Push (☁) icons appear top-right
Right-click in the editor: Push Current Widget · Open Live Preview · Debug Server Script
Keyboard shortcuts: Ctrl/Cmd+Alt+U push · Ctrl/Cmd+Alt+P preview (only when focused in a widget file)

Every command, grouped by area.
