Widget Watch: Page Opener
I think I've just found a slick widget for all you web developers out there: PageOpener. This widget allows you to open any file or URL simultaneously in any or all of your installed browsers. Great for testing purposes, and it works really well, but there's one catch that took me a little while to figure out: on the back of the widget is where you can drag and drop your browsers in order for them to be included in the widget. There's a list of browsers on the back, and text that says "To add a browser, drag the application here." You need to drag the application onto that text, not the list of browsers. It's a little counter-intuitive, given that most other OS X apps with lists like this allow you to drop items directly into the list. However, I'll let this quirk slide since its a widget, and widgets most certainly can be quirky.
Just in case this widget's developer is listening, I have one feature request: dumping browser caches. Safari and others are notoriously horrible with caching while testing sites, and it'd be great to have a simple way to dump across multiple browsers while using a tool like this.
