" summary

Shows concrete productivity moves: switch to the New UI and distraction‑free mode, remove tabs and rely on Ctrl/Cmd+E and Cmd/Ctrl+1 for navigation, use live templates like psvm and postfix templates, prefer type‑aware completion (Ctrl+Shift+Space) and statement completion (Cmd/Ctrl+Shift+Enter) to generate correct code. Demonstrates debugger features that work: stream tracing with Trace current stream chain, emulated method breakpoints, non‑suspending breakpoints that evaluate/log or mutate state, data‑flow analysis for call chains, and language injection for inline SQL.
