Notebooks

Named collections of positions you build or collect — each entry with its own score, cube, and engine analysis — and the filmstrip editor that steps through them.

A notebook is a named, loose bag of positions you've built or collected — each with its own score, match length, and cube state, its engine analysis, and your notes. Positions get into a notebook from the board editor, Create a Position: build or bring in a position there, and save it. Because every entry carries its own match context, one notebook happily mixes "double at 7-away 7-away" with the same position at 7-away 2-away — there is no match wrapper forcing everything to one score.

Notebooks (under Improve in the navigation) is the hub: one card per notebook. Each notebook has an overview page, and the editor opens inside a notebook to step through its entries.

The notebooks page

The hub lists your notebooks as cards. Each card shows up to three preview boards and the notebook's title, with a count and when it was last changed ("2 positions · just now"). Click a preview board to open that entry in the editor; click the title to open the notebook's overview.

+ New notebook creates a notebook and opens the editor inside it, asking How do you want to start? — the Starting position, an Empty board, or an XGID or share link you paste. Those are the same three options as the editor's Set the Board menu, and you can change the board any time from there. The notebook exists from that moment, titled Untitled notebook until you rename it, and it saves on every change: there is no save button, no unsaved state, and a reload never loses an entry. The one exception is a notebook you never touch: leave it with no positions, no title, and no description, and it is discarded rather than left cluttering the hub.

With no notebooks yet, the page says so and offers a link to the editor: you don't need a notebook just to look at a position.

The notebook overview

A notebook's overview page (/notebooks/…, from the card title) is where you tidy it up:

The title and description are edited in place at the top; both save when you finish typing.
+ Add position opens the editor inside this notebook on a fresh board.
The trash icon deletes the whole notebook, after a confirmation.
Below sits one card per entry, labeled by its number and decision — #1 · checker 65, #2 · cube, #3 · take/pass — with the depth of its analysis (Book, Quick, Smart), a star or note marker where you added one, and × to delete the entry. Click a card to open that entry in the editor.

‹ Notebooks at the top returns to the hub.

Editing inside a notebook

Open an entry — from a card, from the overview, from Open in notebook → on the Saved page — and the editor loads it with the notebook wrapped around it. Everything on the Create a Position page still applies; this is what changes:

The header shows the notebook's title in place of "Analyze". Click it to rename the notebook or edit its description. × now returns to the notebooks hub.
The filmstrip shows every entry as a board thumbnail. On a wide screen it is a rail to the right of the board; on narrower screens it runs in a row under the board. The entry on the board is ringed. Click any thumbnail to load it, or step through them with ← and →. Each thumbnail has its own × to delete the entry.
Adding the current board. Edit the board and it stops being an entry: the ring leaves the strip, a Save to notebook chip appears in the action row, and the dashed + tile at the end of the filmstrip offers Add this position to the notebook. Either one files the board as a new entry (the shortcut is S). While the board is an entry, the tile shows a check mark and the chip is gone.
Star, notes, and tags. On an entry the action row holds the same three chips as match review: star (S), tag (T), and notes (N). They are stored inside the notebook itself.
No share chip. Sharing is offered in the lab only (see Sharing below).

Analysis works exactly as in the lab: ambient Quick, Smart one click away, the book for opening positions, and the file's own numbers on a position brought over from an analyzed match.

How entries are stored

Each entry freezes its own match context. The same board at a different score, or with a different cube, is a separate entry — change the score and save again, and both versions sit side by side.
The same board can hold two different questions. The double and the take/pass answering it save as two entries.
Analysis only ever upgrades. An entry stores the best-known result. Clicking Smart on a Quick entry updates it in place; flipping back to Quick to compare never downgrades it. A position brought in with the file's own analysis keeps that analysis.
Saving the same position twice doesn't duplicate it. The chip and the tile both know when the board already matches an entry.
Deleting an entry is one click on a clean entry, and asks for confirmation when the entry carries a star, a note, or tags — deleting it destroys those too.

Notebooks across the app

Saved positions — an entry you have starred, noted, or tagged appears on the Saved page alongside the positions you marked in review. A plain entry does not: a notebook is a workspace, and a star, a note, or a tag is what promotes an entry into your study set, exactly as it does for a match position. From there, Open in notebook → opens it in the editor, and ✕ removes it from its notebook.
Positions browser and Study — entries with analysis join the positions index and the study question pool through the ordinary filters, each under its own match score.
Backups — notebooks travel in a .bgdb export, entries and analysis included. They are not matches: they never appear in the matches list and never count toward your library statistics.

The share sheet is offered in the lab only; inside a notebook the action row has no share chip. To share a notebook position, set it up in Create a Position outside the notebook and share from there — the same sheet as sharing from a review.
