Seeing that you have connections in the highest places, you may want to consider this: The search box where you enter your forecast location gives a list of cached locations. This list contains two 'ingredients':

1. My favorites
2. Locations I once used

[1] contains the names as I've called them initially, but I have renamed most of them. So what I called 'Beach' I later renamed to 'Marina de Rossano'. It is annotatied correctly on the map, but it's still as 'Beach' in the cached list.
[2] contains stuff that I once clicked on, out of curiosity. These locations follow me forever. I want to get rid of them.

The easy way out: allow a 'clear' of the cache of this list. After clearing, add all the favorites. It fixes both problems in one go.

No, I do not want to clear all of the cache; that would involve re-setting all color tables and other stuff that I want to keep as-is. It's just that the list of search items is pretty annoyingly not what I want.
