I helped build browsers. Then I built the extension I missed.
I was an early Chromium browser developer, writing C++. We built the desktop browser ChromePlus — later renamed CoolNovo — which Tencent acquired in 2012, and I kept working on Chromium-based browsers until 2017.
When that chapter ended, I wanted Chrome as my daily browser. What I looked for first was what third-party browsers had taught me to expect: super drag, mouse gestures, a boss key. Chrome had none of them, and nothing on the Web Store filled the gap. So I built it myself: Super Drag started as a basic implementation in September 2017, went up on the Web Store that month, and has been in daily use ever since — thirty thousand people kept it running with me.
Here is my answer to "why rebuild": super drag is practically a standard feature — Maxthon, TheWorld, 360 Browser, QQ Browser, Opera, ChromePlus and many other third-party browsers all ship some version of it. Chrome never did. But Chrome's APIs and the extension platform can do far more today than they could in 2010 — more than enough to rebuild super drag properly. So in 2026 I did: a new engine that classifies a drag once and never touches the DOM while you move (about a twelfth of the cost per frame on heavy pages like YouTube), polite by design — text drops into inputs natively and pages with their own drag-and-drop keep working — a real settings UI in light and dark, and fifty-four languages.
And the rest of what Chrome forgot? Mouse gestures. The boss key. Now that the foundation is right — they're next.
