It would be nice if the app searched for tag=value typed in by the user for more then one click.

I.e. I’ve typed in shop=convenience, clicked on the map once and got all shop=convenience around. Then I clicked again in another place and I got hotels instead of expected shop=convenience.

Thank you for your comment. I implemented your suggestion. shop=convenience or any other key=value pairs in the input fields will be saved for further usage.
