Hi, I have just started to use yEd today and it looks like it will be very useful!
I found that when using Fit Node To Label on a Decision box (diamond shaped), the label text overflows the diamond, because the box size is based on the rectangle around the diamond instead.
I can help it by increasing horizontal and vertical space, but then those settings also apply to other containers.
How can I make a diamond properly enclose its text? Could you add this in a future version?
