Improved - Auto-save: edits save automatically with no data loss. - Multi-select Quick Edit: apply appearance to many selected nodes at once (including children); tap canvas to dismiss; reset covers all selected. - Copy-to-Top: nodes duplicated via transfer come to the front automatically. - Image Stack Group polish: expand, collapse, reorder, delete are smoother and more stable, no zoom jitter. - Canvas performance: stays fluid even with many images. - Fixed a crash when opening projects containing images. - Fixed projects occasionally lagging one version behind. - iOS 26 toolbar button groups: Undo/Redo and Multi-select/Quick-edit grouped; +/− and iPad toolbar stay separate circular buttons. - Long-press detaches a selected child node into an independent node. - Requires iOS 26 or later.

Neuron 1.2 New - Node search: real-time full-text search across titles and notes, with matching nodes highlighted on the canvas and arrow-key navigation between results (iPad: search button in the top-right, ⌘F, Command Palette; iPhone: press and hold on empty canvas). - Elastic connections: lines gently wobble while you drag a node; toggleable in Settings. - Auto-snapshots: every save creates a point-in-time snapshot (keeps the latest 20), restorable with one tap in Settings. - Quick outline editing: double-click a node in the outline to edit its title and notes in place. - Adaptive node text: with a custom node background, text color automatically shifts darker or lighter to stay readable. - Enhanced settings panel: color reset buttons, improved swatch display, and fixed recent-color history. - Improved line drawing: connections stay smooth in every direction with no sharp folds. Improvements - Search, elastic connections, and other features add zero standing overhead, so canvas performance is unaffected. - iPad toolbar buttons animate consistently with iPhone. - New UI text is translated into 6 languages.
