By popular demand, with the latest version of TooManyTabs for Chrome, you may use context menu (right click menu) to send the current tab or any links on the tab to TooManyTabs immediately.
The tab/link can even be sent to different coulmns if you have enabled "custom columns".
Some users have shown concerns on the performance when loading tab previews. Actually you can start to select or sort tabs even though the previews are loading. We believe the previews are useful for users who prefer more visuals, if you prefer less, you can now turn off the tab previews in options.
