I started my second Google Chrome extension today. It's called blinder and will allow to hide certain html-tags on a per domain basis.
The default config will include ad-removal for facebook.
The initial idea was to remove only ads on facebook but the prototype (called lessAds) had a to long dev cycle. Save - Reload extension - reload facebook - see the result. I need this all inside Chrome so I will configure the tags to hide in the options page.
Ah. You wonder what the first extension is? Its something I put together with some people I met for the first time for a GTUG Chrome Battle. We did not win because there was an extension that did the same as ours only better: Search in the content of an open tab.
This is also my first project managed with Mercurial, so expect some tests and problems while I get my head around a distributed VCS.
