It seems like a hotspot always needs to have a color. Is it possible to make it totally transparant? If not yet possible please add it in next version.
This would be very welcome for use with dooropenings where it looks rather strange to have a colored polygon.
You can do that now - just click on Colour and/or Fill colour and adjust the transparency. (screenshot 1)
At the same time, the color of the circles of a point seems to be restricted to black only, please allow for other colors as black is very difficult to see on a dark background.
You can create your own.
Then select using Hotspot properties/Display/Object. (screenshot 2)
