TopSites.me - Add Default Setting: Open in current vs new tab

Let me say first that I LOVE THIS EXTENSION! Thank you!   

One (hopefully small) revision I would appreciate is the option to set my default to open in new vs. current tab.  When I click a dial--forgetting to right click and pick new--my Speed Dial page is gone and I have to open a new one.  I like to keep it open as long as Chrome is open.  

I see others have requested the opposite, so perhaps moving this setting to the default options would make everyone happier?

Thank you!
