This is a very minor issue - not sure I would call it a bug, but I used to be able to press 0 (zero) from anywhere in FS (as long as I was not typing in a text box) and it would take me to the World Map. This worked both with FSH on or disabled. I'm not sure if this was an intended feature but I found it rather handy. Now it does not work at all with or without FSH (it still refreshes the action list on the map but that's it).
However, with FSH turned on, R does much the same as 0 used to but this only works with FSH.
Again, this is rather minor. If it's easy to re-enable this feature that would be great but otherwise don't waste too much time on it.
Keep up the great work.
