BmsTWO adds several dock panels. All are off by default — enable them from View → Views.

Statistics

What: A read-only summary of the current chart.

Shows:

  • Total / playable / BGM note counts and keysound-channel count.
  • Length (mm:ss and seconds).
  • Average NPS (playable notes ÷ length).
  • Peak NPS — the most playable notes in any 1-second window.
  • Per-lane distribution table.

How it works: Computed over all channels' notes; NPS uses absolute times (GetAbsoluteTime), so BPM changes and stops are honored. Peak NPS is a sliding-window scan over sorted note times. Recomputes (debounced) on any edit.

Selection

What: A sortable list of the currently selected notes.

Columns: Pulse, Time (s), Lane, Channel. Click a header to sort (numeric-aware); double-click a row to jump to that note.

How it works: Pulls selection info from the sequence view and rebuilds on SelectionChanged. Pairs well with Select All Notes in Channel.

Charts (sabun workflow)

What: Lists the sibling chart files (.bmson, .bms, .bme, .bml, .pms) in the current song folder, so you can move between difficulty variations that share a folder.

How to use: Save your chart into a song folder, open View → Views → Charts. The open chart is shown in bold; double-click another to switch to it (you'll be prompted to save unsaved changes first). Refresh rescans the folder.

How it works: Scans Document::GetProjectDirectory() for chart files; opening routes through the normal open path (so the save prompt fires). Refreshes on document / file-path changes.

Keysounds (sabun workflow)

What: Manage the shared keysound list (the sound channels) from one panel, instead of per-channel context menus.

Shows / does: Each channel with its note count; buttons for Add… / Remove / Up / Down / Replace…. Double-click a row to make it the channel you're editing (shown in bold).

How it works: Operations call the existing undoable Document APIs (InsertNewSoundChannels / DestroySoundChannel / MoveSoundChannel / SetSourceFile). The list refreshes (debounced) on edits and tracks the current channel.

Multi-track sample preview

What: Preview several selected channels mixed together, rather than one at a time.

How to use: Select multiple channels and trigger preview; their sources are mixed for the preview playback.

How it works: The preview path gathers the selected channels and mixes their sample sources.

BGA & Stops docks

These editing docks are documented under Editing & Navigation (BGA editing, STOP events).
