FujiyNotepad v4.8.0

FujiyNotepad is a fast viewer for very large text and log files. v4.8.0 is a big feature release: bookmarks, theming (including High Contrast), log-triage tools, and quality-of-life actions.

New features

• Bookmarks - mark lines (Ctrl+F2) and jump between them (F2 / Shift+F2); marks also appear as ticks in the new scrollbar margin, alongside find-match positions.
• Themes - pick System, Light, or Dark for the whole app and the text surface. The text now also follows Windows High Contrast mode for accessibility.
• Show Whitespace - reveal spaces, tabs, trailing-space runs, and control characters as markers; the status bar shows the file's line-ending style (LF / CRLF / Mixed).
• Filter / grep export - copy or save just the lines matching the current filter.
• Timestamp delta - select two timestamped log lines and the status bar shows the elapsed time between them (e.g. "delta = 2m 30s") - quick triage of how long something took.
• Quick actions - Copy File Path, Reveal in Explorer, and Copy with Line Numbers.
• Crash diagnostics - if the app ever closes unexpectedly, the exception is written to %LOCALAPPDATA%\FujiyNotepad\crash.log to make bug reports easier.
• A revamped Open Sample (File > Open Sample) that walks you through all of the above.

Improvements and quality

• Accessibility, async, and theming best-practices pass across the WinUI app, plus a subtle visual refresh of the find / filter / status surfaces.
• New app-layer UI tests drive the published app through UI Automation in CI; engine and logic test coverage is now shown in the CI summary and gated at 85%.
• Internal refactors for testability (device-free presentation layer, deduplicated test helpers, extracted status/parse helpers).

Install

Download the zip for your architecture (win-x64, win-arm64, or win-x86), unzip, and run FujiyNotepad.WinUI.exe. The build is self-contained - nothing else to install.
