The idea is to make it easier to see...
Currently, when you have a lot of tabs, you have to frequently glance down!
This is inconvenient because we are usually focussed in the top left of the screen. (where the text starts on the page view).
As such, the best place to put the tabs we're currently working on will be near the top.
The older tabs should be at the bottom.
(The concept is similar to webpage design. The prime view estate is the top part. The bottom parts is not where the eye lands first.)
