Features
- Theme customization with Material Theme palettes. Restyle the app with built-in Material Theme color palettes. The theme picker now lives in Settings.
- Redesigned Settings. A wider Settings modal with Zed-style setting rows, toggle switches in place of checkboxes, and the language and theme pickers moved inline. The footer has been removed.
- Workspace side panel. A new side panel for workspace settings, with an ask-before-close prompt so you don't lose unsaved work.
- Window polish. Long filenames now scroll as running text, the footer is persistent and resizable, and the titlebar is centered.
Performance
- Large spreadsheets open much faster. A ~71k-cell
.xlsxthat previously took around 3 seconds to open now loads in well under a second. Only the visible sheet is parsed up front (via lazy reading), so switching sheets no longer re-parses the entire workbook. - The app is much smaller. The installed app shrinks from ~25 MB to ~10 MB, making downloads and updates faster.
Fixes
- macOS resize lag. Fixed a white gap that trailed the window during live resize on macOS (WKWebView).
- Titlebar dragging. Fixed titlebar drag behavior.
Experimental (off by default)
- Inline cell editing with write-back to the source file, and session-scoped undo/redo, are landing behind feature flags and are not yet enabled.
macOS — first launch
Builds are unsigned, so macOS may report the app as "damaged". Remove the quarantine flag once, then open normally:
xattr -dr com.apple.quarantine "/Applications/LazySheet.app"Linux — which file?

Blank window on Fedora/Arch with AppImage? Prefer the
.rpmpackage instead. The AppImage EGL clash is fixed in releases after v0.4.0; if you're on an older version see the README troubleshooting section.
