Similar to how Quick Tabs does it - they only show the results that match what you type in the search box and put the focus on the top one, so that when you press enter it opens that tab immediately.
Current flow in Quick Tabs: type -> enter -> done
Current flow in Session Buddy: type -> scroll down the tabs list to find the highlighted tab -> identify the top highlighted tab -> navigate with your mouse to that tab -> click -> done
While Session Buddy is definitely more visually pleasing, it's not nearly close to the efficiency of Quick Tabs at this point.
