Looq upgrades Quick Look for dev files

This is the kind of utility that looks modest on paper but saves real time in daily use: if you live in Finder, repos, or raw data files, Looq cuts out a lot of context switching.

• –Markdown support goes beyond basic rendering, with GFM, math, diagrams, GitHub-style alerts, and an auto-generated TOC sidebar.
• –The code viewer covers 190+ languages and adds practical touches like line numbers, custom fonts, tab width, word wrap, themes, and shebang detection.
• –CSV, TSV, SQLite, diff/patch, ZIP, TAR, and folder previews make this a broad “peek before opening” tool, not just a markdown viewer.
• –The privacy angle is a real differentiator for a file utility: local-only operation and zero analytics are strong selling points for sensitive projects.
• –It feels like a polished power-user extension more than a flashy launch, which is exactly the kind of app that becomes sticky.
