Hey,
Well since all of us users usually work on multiple tabs opened and usually we need to sort tabs inside columns which are provided, and using these columns sometimes takes so much space on the screen specially so i suggest to add a feature that allows columns to expand and collapse on hover which will keep our working area taking most of the screen and whenever we hover over a collapsed columns it expends to take a wider area on the screen, this feature can easily be disabled in the menu for users who has bigger screens and wish to be able to view all the columns simultaneously.
So what do you guys think?
