Each shape can have an icon that can be set in a certain position around the shape.
This is actually a very good feature. We can use that icon to mark a shape or in my case a “component” with various things such as based on their type or perhaps priority (1, 2, 3 etc.) or many other possibilities but unfortunately the icon list is very limited which makes it less usable.
I wish instead of that limited icon list, we could see the entire emoji icons we normally see in mobile phone keyboards. That list has different tab categorising the icons (or rather smileys) and a lot of those smileys are useful.
