Feature Request: Better controls in the zoom map

[somnambulistic]

1. It would be helpful if the zoom window had a preset magnification selector (e.g., 10%, 25%...100%, 150%, 200%, etc) or the ability to manually enter the magnification. I find myself using the zoom window at high mag levels (200+) when using the slope map and it gets a bit tedious to keep clicking the + button.

2. It would also be helpful if the magnification setting was persistent when the window was closed.

Number 2 has been implemented in version 20.2. Number 1 is mostly a problem of finding an unobtrusive way to integrate such a feature into the UI without making the window bigger.
