I have been using sublime text with 2 columns for a while, and you can change focus of columns with alt + 1, alt + 2 etc. But when you use alt + tab (next_view) you are also changing columns. Then you get to the end of focused one cursor goes to the other files in second column. I would like not to change focus when I use alt+tab, I mean to remain in one column then alt-tab-ing.
