Settings¶

Everything under Settings > Osmosis. Osmosis uses Obsidian's declarative settings API, so every one of these is findable from Obsidian's own settings search.

Mind Map¶

Setting	Default	What it does
Branch line style	Curved	Default geometry of the lines between nodes — curved, straight, angular, or rounded elbow. Per-map styling overrides it
Max node width	230 px	Default width at which node text wraps. A map's own Max width overrides it
Highlight transcluded branches	Off	Visually distinguish nodes embedded from another file
Expand transclusions	On	Load embedded notes expanded when a map opens. Off starts them collapsed and loads on first expand
Default mind map mode	Editing	Which mode new maps open in — Editing, Reading, or Reading on mobile only. See reading mode
Cursor sync	On	Clicking a node scrolls the editor to its line, and vice versa

Undo history¶

Setting	Default	What it does
Undo steps	50	Maximum map undo history kept per mind map
Undo memory cap (MB)	20	Ceiling on the memory that history may use. Whichever limit is hit first drops the oldest edits

Spaced Repetition¶

Setting	Default	What it does
Daily new card limit	20	Maximum new cards introduced per day (0 = unlimited)
Daily review card limit	200	Maximum reviews per day (0 = unlimited)
Learning steps	`1m, 10m`	Intra-session steps for new cards
Relearning steps	`10m`	Steps for cards you rated Again
Include line cards in decks	On	Count line cards in deck totals and sequential study. Off keeps them studiable in place only. Per-note override: `osmosis-line-cards: false`

Review History¶

Setting	Default	What it does
Review log folder	`Osmosis/Reviews`	Where the review log is written. Changing it moves the existing files
Device name	Auto-detected	Labels this device's log files so no file ever has two writers. Leave empty to detect

Keep the log out of search results

Add the review log folder to Settings > Files & links > Excluded files. The files are generated Markdown, so Obsidian indexes them like any note unless you say otherwise.

Study Mode¶

Setting	Default	What it does
Show deck breadcrumb in study modal	Off	Show which deck the card on screen belongs to
Line card context lines	2	How many preceding sibling lines appear as context on a line card's front in sequential study (0 = breadcrumb only)

Note Inclusion¶

Four lists decide which notes generate cards at all. See Decks.

Setting	What it does
Include folders	Notes in these folders generate cards without `osmosis-cards: true`
Include tags	Notes carrying these tags generate cards without `osmosis-cards: true`
Exclude folders	Notes in these folders never generate cards
Exclude tags	Notes with these tags never generate cards

Folder and tag fields autocomplete against your vault. Tags match hierarchically, so archive also covers archive/2024.

Exclusion always wins

A note in an excluded folder generates nothing, even with osmosis-cards: true in its frontmatter or a matching include rule.

Per-Note and Per-Map Settings¶

Some settings aren't global at all — they live in the note:

Where	Key	Controls
Frontmatter	`osmosis-cards`	Whether this note generates cards
Frontmatter	`osmosis-deck`	This note's deck
Frontmatter	`osmosis-line-cards`	Whether this note's line cards count in decks
Frontmatter	`osmosis-styles`	This map's layout, theme, and per-node styles
Fence metadata	`deck`, `hint`, `bidi`, `type-in`, `exclude`	One card
Properties sidebar	—	Everything in `osmosis-styles`, with a UI
