Design Philosophy
> "Software should respect your documents. They stay on your computer, under your control."
OpenReader is built around a single idea: a PDF reader should feel like a well‑made tool, not a web page. The interface follows native Windows conventions — real menus, keyboard shortcuts, proper window management — with a refined dark theme (Tokyo Night‑inspired) and a clean light option. Every interaction is immediate, every feature discoverable without tutorials.
The focus is on reading and working with documents, not fighting the interface. Toolbar buttons have clear vector‑drawn icons, tabs are movable, zoom is instant, and the reading view puts your document first.
