FR: Allow extension views to be defined as a fixed height.

Would it be possible to have a view where the height is defined as a fixed value, rather than scaling proportionally to the size of the view container. For example, I often move code between a vertical and a horizontal monitor. In my side bar I have a few small panels which I never want to change height.  When I change to the vertical monitor. Those bottom two panels which I have set the height to exactly what I want, then get scaled.  What would be ideal is a field in package.json that lets me specify that this panel should be fixed height, and that if the viewport changes, these panels should not be scaled unless unavoidable. If the views are forced to scale, then they should ideally remember the value the user set them to and try and return to that value when more space is available again.
