Action List & Filtering

The action list is the sidebar on the match-review screen: every checker move and cube decision in the match, in order. For a long match that's hundreds of rows, so the filter panel above it lets you narrow the list to just the decisions worth studying. Toggle the whole sidebar with the [ key.

Reading the rows

Each row carries an error dot on the right — round for checker moves, square for cube decisions — colored by severity along the same ramp used everywhere in the app: green (good) → yellow → orange → red (blunder) → magenta (howler). The bands and their colors are explained in Match Statistics.

A few row markers are optional and controlled in User Settings: the green good-move dots, the joker luck column, and whether intermediate checker hops are collapsed in move labels. A star or pencil icon marks starred or annotated positions, and phase dividers break the list where the phase changes.

The filter panel

The panel sits at the top of the action list, collapsed by default into a one-line summary of what's currently active (e.g. "Starred · errors 0.02–0.08" or "No filters"). Click the summary to expand the controls; it auto-collapses again as soon as you move to another action, keeping the list tall.

Quick presets

Above the axes is a row of one-tap presets. They're all just that — presets: each one is a shortcut that sets the filters to a common view. Tap one to apply it; tap it again to clear it. The lit preset is whichever one matches your current filters (touch an axis by hand and none stay lit). There's no layering and nothing to combine — a preset is the whole view, not a piece you stack on another.

The ones that trim how much of the list shows:

• All — every decision, unfiltered.
• No obv cube — hide cube decisions the engine considers obvious.
• No obv. — also hide forced and effectively-equal checker moves.
• XG mode — all checker moves, but hide obvious cubes and correct no-doubles (the same browsing mode eXtreme Gammon defaults to).

The ones that jump to a category of mistakes — these also switch the list to all games (except this game), since that's how you'd want to view them:

• All errors — every error (and worse), across all games.
• Your errors (this game) — just your mistakes in the current game.
• Your errors (all games) — your mistakes across the whole match.
• Starred — only starred or annotated positions.

(The "your"-scoped presets need a profile set on the match; they're disabled if you weren't a player in it.)

The filter axes

Under the presets are the individual axes the presets drive. This is where you customize — touch any axis and you're no longer on a preset, you're on your own combination. The axes combine: a row must pass every active axis to appear.

• Player — All, or one side, by who made the decision.
• Checker moves — All, No obvious (hide forced / equal moves), or None.
• Cube decisions — All, No obv. (hide obvious cubes), Action (also hide correct no-doubles — only cubes worth reviewing), or None.
• Error severity — All, Errors, Blunders, Howlers, or Custom. The named options snap to your configured thresholds; dragging either end of the equity-loss range slider switches to Custom. Only analyzed decisions with an equity-loss figure pass this axis. The bands come from your User Settings, and equity loss itself is explained in Performance Rating.
• Starred — All, or Starred: positions you've starred or annotated (given a note or a custom tag).

One game or the whole match

A scope control switches between the current game and all games. In single-game scope a Jump to game dropdown lets you hop between games (each labeled with its score); in all-games scope a Phase of game dropdown jumps to the first move of each phase — Opening, Middle game, Endgame contact, Race, Bear-off.

Controls at the bottom

Below the list is the navigation bar — the controls that step you through the filtered list. The four arrow buttons (with matching keyboard shortcuts) are:

• Previous / next error (Alt+↑ / Alt+↓) — the red-tinted outer arrows. They jump straight to your mistakes, using a separate navigation threshold (distinct from the visible error bands) so you can hop only between severe blunders without recoloring the list — set it in User Settings. Hold to repeat.
• Previous / next action (↑ / ↓) — the inner arrows; one step at a time.

Between them sits a three-way player-scope toggle (one side · Both · the other). It restricts the arrow navigation to a single player, independent of the Player filter above — so you can leave both players visible in the list but walk the errors of just one side.

The buttons flash when triggered by their keyboard shortcut, confirming the key registered.
