The new call sign window is fantastic! No more missing callers! The info displayed when you hover the mouse over a call is much easier to read than in the older versions. BUT could it be possible to add an option to display the distances in miles instead of kilometres? If it's already there I haven't been able to find it.
Another suggestion... On the wanted states, grids, etc. pages in the settings perhaps you could add 220, 432 and maybe even 1296?
