Is it possible to open multiple tabs in each of the columns. Like I would like to open two Bible in the Bible column and two commentaries on the resource panel. I don't mean tiled one above and one below but i mean one that is hidden until i click the tab and one that visible. It is what i think of when i click the open, that it is adding a tab with the new resource but it always replaces the tab i have. In all reality it would but be opening a new resource except it will remember the previous resource on the top to click back to.
