I would like to see a zoom tool on the world map. As it is, it takes a lot of time moving around the world map looking for barbs and city's alike. I do like the "go to tool " but will only help if you know the target location.
Moving to suggestions & ideas. This hasn't been materialized yet for technical reasons but we are aware of the need, so consider it planned still. It's worth noting that you can use the built in browser zoom in the meantime (usually control + and control -) and for the most part it will work as you would expect.
