SteveTheKiller/KillerPDF

A big release: major new features, a full visual refresh, and an internal rewrite.

New

• Tabbed documents - open several PDFs at once, each restoring its page, zoom, and view
• OCR built into the exe (Tesseract) - OCR a page or dragged region to the clipboard, make a scan searchable, or extract all text; extra languages download on demand
• Digital signatures with a cloud certificate (Certum SimplySign), reusable signatures, and click-to-sign form fields
• Transform tool - rotate, scale, flip, and straighten a crooked scan, with live preview
• Edit existing text by double-clicking a line (the original is cleanly covered)
• Line tool, refreshed draw/highlight bars, resizable word-wrapping text boxes, and a full RGB color picker with eyedropper
• Print options (scale, position, margins, two-sided), page-number stamping, folder/.zip import, Document Info (F12), and recent files with file-type icons

Changed

• New logo, icons, fonts, and colors throughout
• Six themes with per-theme accent colors; sidebar docks left or right; toolbar style picker
• Internal rewrite: the ~15,000-line main window split into ~40 focused files (no behavior change)

Fixed

• True 300 DPI printing, encrypted/damaged PDFs open on a background thread with a repair fallback, form fields render in every view mode, and undo is one item per press
