If I had only one recommendation, it would be to add a custom "marker" design, or at least offer the standard "pin" icon or a "dot". I have many locations and some of the icons take up too much room on my map unless I zoom in farther.
Hi, thank you very much for your review.
It is not so easy with icons, because the Google Markers are not displayed by one icon only. The Marker includes set of icons + their shadows and coordinates of the active area.
Creating marker icons is not so easy, so it cannot be implemented to Joomla! extension easily :-(
Thank you, Jan
