Add manual focus and exposure buttons on Navigate tab
Feature request
Summary
Several people on the forum requested a +- z-axis button on the `navigate page of the web app. This is either because they are using touchscreen, or because the keyboard shortcuts are not well publicised.
There sidebar has only a few items, so there is space for [focus up] and [focus down] buttons. (with mouseover
saying page up and page down)
There is probably space for a software cursor pad, but click-to-move exists for a calibrated stage.
Putting a [brighter] and [darker] and/or [auto exposure] button here would be great as well. links to #240
