I have a few more questions.

a. When I am in a mode with more tabs, selecting one tab it becomes the most 
left tab, near the mode button. Is there a setting to left the tab at its 
position? How are the tabs ordered? When I have multiple tabs open in a browser 
they remain there, don't move to the most left position just because I have 
selected one of them..

b. When a buffer is modified and not saved, one expects the tab changes some of 
its elements, usually a "star" shows up or the buffer name change color. Is 
there a setting to have this?

I am afraid of all this questions but I'm almost done..
