fix width or fixed taskbar button location on taskbar

I want to be able to have task button have a fixed width.  When opening new programs, the width of the task button changes, which moves the position of the task.  But I want the task to be in the same position.

Alternatively, the user could pin the task button EXACTLY in a fixed position on the taskbar, with a fixed width. 

This would really help to keep things organized as I open more tasks on a single desktop.
