Edit existing marker

[Krimatoria]

It would also be great to be able to edit the label and change the icon itself (well, choose: tower, pickaxe). And sometimes you put a mark quickly, in your head you remember how you wanted to sign and what the structure was, because sometimes they chase you and there is no time to choose, but you want to have time to put any mark. And then you want to change it. And we have to clean the card again, remove one label, put a new one, and so on.
