Also i think, it will be interesting if properties, like:
Top, Left, Width, Heigth was somewhere near from each other.
Or like it screenshot grouped by +. maybe by some setting.
And about this feature (explanation of properties) - for me, as the Lasarus new user, it will be useful, i don't know about this.
And if not this topic i will not know about it. And maybe there is sense to do it as default.
