Summary
DeepSeek TUI PR #3788 implements the Hotbar feature while making it hidden by default for v0.8.66. The release approach keeps power controls available without adding default interface noise during stabilization.
What changed
DeepSeek TUI added a configurable Hotbar with title-level shortcut visibility and a once-only launch nudge, but kept the feature hidden by default.
Why it matters
Agent tools are struggling to expose richer controls without overwhelming active coding sessions. Hiding the Hotbar by default shows a product choice toward progressive disclosure during a stability-focused release candidate.
