 A native Linux deck and game tracker for **Magic: The Gathering Arena** running under Steam/Proton.
 It follows MTGA's `Player.log`, much like Untapped.gg and other trackers do, and shows:
 
-- **My deck**: remaining library with draw odds, hand, battlefield, graveyard, exile, sideboard.
-  Between matches, it shows the last deck you submitted.
-- **Opponent**: battlefield, stack, graveyard, exile, cards *known* to be in their hand or library
-  (cards you saw that went back into a hidden zone, or were revealed), and every card seen this match.
-- **Card preview**: hover a card to see its image from [Scryfall](https://scryfall.com).

+- **Match**: life totals, poison/energy and other player counters, emblems, hand/library/graveyard
+  counts, turn timer and timeouts used, turn/phase, Bo3 score and game time. The deck view fills
+  the bottom half.
+- **Turn**: what happened this turn, for you, your opponent and in total: cards drawn, spells cast,
+  lands played, creatures died, life gained/lost, damage, discards, mills, exiles, counters and
+  tokens, plus land drops used/allowed. Use ◀ ▶ to browse earlier turns; the "Whole game" table
+  shows game totals.
+- **History**: every finished game with date, event, opponent, both decks' colours, who was on
+  the play, the result, turns and length. Click a game to open it in the Deck/Match/Turn views
+  ("Back to live" returns). Games from the previous MTGA session (`Player-prev.log`) are imported
+  on startup.

+The Match view also shows who was on the play and, in best-of-three, who has been on the draw more.

+*⚙ Customize* shows or hides the items in the current view. *Customize → Arrange…* lets you
+reorder (drag, or ↑/↓) and show/hide the sections of the My deck and Opponent panels, or the
+rows of the turn view. Your choices are remembered.
 
 Card names, mana costs and types come from MTGA's own local card database, so they work offline.
