 - Early CLAP plugin support via nih-plug, baseview, and egui. Feature-gated builds separate CLI from plugin targets.
 
 ### Forth Language
+- Removed `chain` word (replaced by pattern-level Follow Up setting).
 - `case/of/endof/endcase` control flow for pattern-matching dispatch.
 - `bjork` / `pbjork` — euclidean rhythm gates using quotations: execute a block only on Bjorklund-distributed hits.
 - `arp` — arpeggio list type that spreads notes across time positions instead of stacking them simultaneously.

 - Reverb parameter words added.
 
 ### Engine
+- Follow-up actions: patterns now have a configurable follow-up behavior (Loop, Stop, or Chain to another pattern). Replaces the Forth `chain` word with a declarative setting in the Pattern Properties modal (`e` key). Chain targets specify bank and pattern via UI fields.
 - Delta-time MIDI scheduling for tighter, sample-accurate timing.
 - Tempo and current beat exposed in sequencer snapshot.
 - Spectrum analyzer rescaling.
 
 ### UI / UX
+- Patterns view redesign: new layout with banks column (showing pattern counts), expandable detail rows for the focused pattern (quantization, sync mode, progress bar), and a bottom preview strip with mini step grid and pattern properties.
+- Smooth playback progress: playing patterns display a real-time progress bar interpolated between steps.
+- Dynamic step grid sizing: `steps_per_page` adapts to terminal height instead of using a fixed constant.
 - Mouse support: click navigation on the pattern grid, panels, and modals.
 - F1–F6 page navigation across the 3×2 page grid.
 - Collapsible help sections with code block copy.
