Node selection

[#1]

  When we select a node by indicating its number, it is marked with a green color spot in the structure but if the structure is a little more than simlpe it's difficult for the user to see where it is... It should be marked by a different (more clear) way, for instance the node could be enclosed in a small circle in order to be visible.

on display options , mark " display atributes only for seleceted elements " and then click to show node number.you will easily find it

  I didn't notice any big difference in the visibility by choosing this option..
