Hi Tim,

Thanks for the feedback and sorry for the late reply.

Thanks for the update! Maybe I missed it, but what is planned to eventually

The common usage is to put a label or sign of a place. Something like this
in Google map. In this case, the sign is better to have the same size and
always facing the same direction. When we zoom out, we can see where is the
place since the billboard will still have the same size. And when we rotate
or tilt the map, we can still see it properly also.

In my last week report, it's getting better, like the screenshot below.

Regarding a tooltip or a label text, I haven't thought about it. I am not
sure it's possible to do it even for a normal symbol. Using the identify
tool is one of the option to know what is it in the billboard.

Another good example of a billboard is this

I hope my explanation is quite clear.

Best Regards.
