The Timeline Returns

The timeline from TheBrain 14 is back: a strip below the plex showing your events on a zoomable time axis.

• Drag the background horizontally to pan and vertically to zoom — or use the mouse wheel or trackpad pinch
• Click on the timeline to create an event, or drag to create an event and set its duration in one gesture
• Drag events to reschedule them
• Jump around with day/week/month/year views and a mini calendar
• Choose between classic angled flags and a new chip-style event display
• Switch between the timeline and the day navigator panel using the rightmost icon in each view's toolbar

Callouts in Notes

Highlight important information with callout blocks — colored, icon-labeled blocks such as Info, Tip, and Warning.

• Insert any of 13 callout styles from the notes editor menu
• Customize each callout type's colors, icon, and title style in the theme editor
• Callouts convert to and from markdown, compatible with Obsidian

Brain Themes: Complete, Plex, and Content

The Brain Theme settings are redesigned around theme templates.

• The new Complete Themes gallery pairs a plex theme with a content theme and applies both in one click — 28 matched pairs are built in, and you can create your own combinations

• Separate Plex Themes and Content Themes galleries let you apply, rename, import, export, and save your own templates — custom themes now sync across your devices, including on the web

• Sort galleries by hue, brightness, name, or most recent, and filter to just your own themes

• Content theme thumbnails now preview each theme's real fonts and heading styles

• After trying themes, one click restores the theme you started with

Faster Notes Editing on Large Notes

Major performance work in the notes editor, focused on very large notes.

• Notes open much faster — content appears almost immediately and the remainder fills in seamlessly in the background

• Typing is much more responsive

• Saving is significantly faster

Faster Tables in Notes

Notes containing large or many tables are now much quicker to work with.

• Notes with many tables load in a fraction of the previous time

• Typing in table cells is now smooth even with thousands of cells

Import from More Apps

• New importers bring your notes into TheBrain from Apple Notes, Dynalist, Google Keep, Joplin, Notion, OneNote, and Workflowy — found under File > Import Brain, each with step-by-step instructions.

• Markdown imported from other apps or pasted into notes is now converted more faithfully, including tables, bullets, task lists, and italics

• Print and PDF export preview now shows true document pages with margins, page breaks, and zoom

• Backlinks and unlinked mentions in the notes footer now have a context menu for working with the link

• Tab now moves through the create-thought dialog's fields in a predictable order

FIXES AND IMPROVEMENTS (15)

• Fixed: Clicking in the plex didn't always return focus to the search box

• Fixed: Typing while a menu or dialog was open could reach the controls behind it

• Fixed: Esc didn't close a dialog while the cursor was in one of its text fields

• Spellcheck no longer stalls on long documents with many flagged words

• Spellcheck now updates as you scroll and right after you type

• Spellcheck and dictionary settings changes apply to the open note immediately

• Pressing Esc in the Settings search or BrainBox filter now clears the text first; a second Esc closes the panel

• Notes: Better handling of moving the cursor above, below and between tables, blockquotes, code blocks and other elements

• Fixed: The link type name field could lose focus while typing in the Link Types editor

• Fixed: An AI response interrupted mid-stream was discarded

• Fixed: Drag-selecting text in a table could fail when another table had been active

• Fixed: Freezes when navigating away from a note containing large tables — switching thoughts is now instant

• Fixed: Arrow-key navigation didn't move the cursor or scroll when the next table row was out of view

• Fixed: An error could occur when opening account dialogs before account details had loaded

• DESKTOP Fixed: Exported PDFs could render with substitute fonts
