Or will you use -o flag to ignore the projection check?

This is a good point. I can see that. However, manual is also useful for
this. This is what I use. Works for command line programs too.
To satisfy everybody, I suggest to provide a buttons with something like
"Take me to LL", "Take me to default location" and "Take me to XY". What do
you think about that?
But the real improvement should be the messages which would guide you
through the process.
Perhaps we should move this discussion to a different thread and leave
