Margin for the ResetAllAxis command and take into account annotations

I'm using heavily the "reset all axis" functionality in my application, but I don't like the fact that the axes are set exactly at the minimum and maximum points. I would like to be able to add a small margin (in pixels maybe?) so that the points are not completely on the end of the axes.

Also, I would like to have a way to force annotation to be took into consideration for the reset axis. I use some annotations to display information and I would like that the annotation is displayed completely when the user reset all the axis.

Maybe something already exists, but I didn't find it.

Thanks
