v1.4.3

Features

• Precise progress bars — context and progress bars now use partial-fill blocks for accurate visualization
• Checkpoint density bar — new checkpoint bar aligned with context bar, showing checkpoint count vs context size
• Prompt progress percentage — shows PP (prompt processing) speed with a percentage indicator
• Animated download spinner — download modal status line now shows a spinning indicator with percentage during model downloads

Fixes

• Prompt progress fraction — corrected 0-1 fraction to display properly (was treated as percentage)
• Checkpoint bar alignment — uses nCtxSlot to align with context bar
• Checkpoint stale state — slot.checkpoints now cleared on slot release, matching server behavior
• ProgressBar width — uses full available width instead of reserving unused space

Refactoring

• ProgressBar simplified — reduced to single-row bar-only widget, removed unused percentage label
• Checkpoint display simplified — removed visual bar, now shows numeric count and total size only
• Dead code removed — deleted unused ProgressDialog widget, removed dead ProgressBar from VersionsTab
• Single-state context bar — simplified to show only prompt tokens
• Removed unused ProgressBar from ModelsTab
