Google Maps: How to add numbered or lettered markers? - google-maps

Is there a simple way to add numbered gmarkers onto a map? Much like how maps.google.com plots them as A-Z.

Google Maps API Icon Maker is an open source utility that has an option to create labeled markers (as well as use a custom color and size).

Google Maps marker drop on building not street

I'm currently making a custom map using the Google Maps API. So far I have inserted a kml layer using geoXml3, and have written the code to determine if the location of the marker (dropped by an autocomplete address search) is contained within the kml boundary.
Unfortunately I seemed to forget that the marker drops on the street outside the building, not the building itself. This is important as the kml layer is over buildings, and doesn't bleed on to the street.
Is there a way to get the marker to drop on the building instead of the street? If not, are there any alternative ways I could complete what I'm trying to achieve?
Cheers.

Google Maps v3 block map interaction

I am trying to make a Polyline editor, just like the one from Google Drawings Library. (for specific reasons, i can't use that one)
It works on the same principle. Start with a point, then for each click add new points and make the polyline.
On the editor from Google Drawings Library, while you are editing a polyline, you're mouse can't interact with other items from the map.
Inspecting with firebug, i see that they have an overlay of 20000000 z-index inside the map.
Is there any way of creating the same overlay for my map using default Google Maps functions?
It's a custom overlay inside the overlayMouseTarget-pane with the same size as the map and a draw-method that updates the position of the overlay. You may do the same.

Look at the InfoBox from the utility libraries. There is an example in the documentation.

Add labels to polygons in google maps?

How do I put a text label on a polygon in Google Maps? Documentation deals with markers and icons, but I don't want a marker - this is not a point. ELabels was good but was made with V2 and breaks with V3.
Create an custom Overlay , you may place there any html-markup (e.g. an element that contains some text)

Google map API v3 markers overlapping

I am making an application with google maps.
When markers are overlapping only the last one is displayed even if the icons are different..
I do not want it to cluster in that case, rather it should show both maybe by changing the coordinates just a but??
Any solutions??
I think this is a pretty elegant solution, called Spiderfying the markers.

I'm thinking of using it.
What I do now is use JavaScript to make a fancy popup that hides and shows divs on one marker location (created problematically in PHP, but you could do it on JS too). It has the side benefit of allowing less markers on the map.
Click a black numbered marker on this map to see it in action.

Another option is to use Google Maps API 3 Utility Library, it has a Marker Clusterer.
