I would like to be able to choose a fixed width / monospace font for at least the Navigation UI panel.
The primary reason is for consistent alignment of hosts that follow a naming convention. It would be much more pleasing and functionally easier to look at if things aligned.
Would be nicer if they could be displayed with a fixed width font. I don't see options to make this happen. Looking at Windows version right now, but I use both the Windows version as well as the Mac version.
Every update I'm still looking for this feature to be added.
the latest release allows you to change the treeview/grid font, size and spacing in the View->Options->User Interface settings.
