So long, taskbar thumbnails! Aero Peek gets disabled in Chromium
Citing usability issues, the latest Chromium nightly builds have switched off support for Aero Peek. Said Chromium developer Hinori Bono, it will remain switched off "until we find solutions that avoid flooding users with tab thumbnails." As with a number of other features in the browser, support for Aero Peek is still built-in but it's hidden behind a command line switch. To re-enable in Chromium, just append --enable-aero-peek-tabs to your shortcut's target field.
I'm somewhat surprised it took this long for a command line switch to be added. On previous posts, there's been no shortage of grumbling over the taskbar thumbnails from Chrome users.
Hopefully if support is re-enabled by default they'll leave a similar switch in the Chromium code --disable-aero-peek-tabs so we can decide for ourselves whether or not to utilize the feature.
