Suspends all but the current tab, and one simply clicks on a suspended tab for it to open automatically. Perfect.

Really good addon but with limited capabilities.
It's good if you want to suspend all of your tabs at once.

This replaces all tabs with a white page with a link to the URL that was there. It has an option to suspend just the selected tab, but clicking it nonetheless suspended all tabs to the right (the wrong option), making dozens hard to access. Crude.

Should be one-click; doesn't need a menu for such a small difference in function. That functionality should be changeable in a configuration page.

Also, needs a suspend inactive tabs after x seconds/mins - timeout feature.

basic, but works!
no whitelist
no timeout settings
does not suspend the active tab in each window
