1.2.0 - New Features

[1.2.0] - 2026-03-23

New Features

• Focus Mode — A new toolbar button (⤢) hides the header, sidebar, and bottom links, leaving the editor as a full-viewport writing surface. Exit by pressing Escape or clicking the "Exit focus" button that appears in the top-right corner.
• Export as .txt — Right-click any tab to download its content as a plain .txt file named after the tab. Works on background tabs too (no need to switch first). Available in the tab context menu alongside Duplicate and Close.

Visual Improvements

• Dark theme redesigned — The default dark theme now uses charcoal gray tones (inspired by Notion's dark palette) instead of the previous blue-navy gradient. Backgrounds, surfaces, modals, and toasts all updated for a warmer, less blue-tinted feel.
• Default accent color changed to Blue — The out-of-the-box accent is now Blue (#3b82f6) instead of Teal. Existing users with a saved preference are unaffected.
• Editor focus border removed — The purple glow that appeared around the editor on focus has been removed for a cleaner look.

Bug Fixes

• Light theme toggle switches — Toggle switch tracks in the Settings modal were nearly invisible on the light theme. They now have a visible inset border when off, which clears cleanly when toggled on.

Version [1.1.0] - App Improvements

[1.1.0] - 2026-03-21

Improvements

• Collapsible sidebar — The tab sidebar can now be collapsed to a slim 32px strip to give more writing space. Preference is saved to localStorage and restored on reload. Defaults to collapsed on mobile and expanded on desktop.
• Sidebar toggle button — A chevron toggle sits at the top of the sidebar. When expanded, a "Hide" label accompanies the icon. The Add Tab (+) button remains visible in the collapsed strip on all screen sizes.
• Mobile header overflow menu — On mobile, secondary actions (Settings, Undo, Preview, Find & Replace, Clear) are tucked behind a ⋯ button to prevent cramping. Copy and the save indicator are always visible. The overflow panel drops as an animated card below the header and closes on outside tap.
• Mobile header layout fix — The header is now a single non-wrapping row on mobile, so the Live Sync indicator appearing no longer pushes buttons to a second row. The sync indicator is compacted to an icon-only badge on mobile.
• Overflow panel animation — The secondary actions panel slides in with a subtle scale + fade animation when opened.
• Stacking fix — The header is raised above the editor container on mobile so the overflow panel always renders on top of the writing area.
