QGIS » QGIS Application

Hi,
I just faced following problem (QGIS 1.7, Windows) - I created a nice symbology for my point layer. Finally, I found out that I need one more class. Unluckily, the class was added on the beginning of the group so I had classes in this order:

class; range
6; 50-100
1; 0-0,5
2; 0,5-1
3; 1-2
4; 2-25
5; 25-50

so I had the class with biggest values first, and then finally the rest in correct order. I tried to correct this, but the only way I found, was to edit the style in text editor. It would be nice ho have more user friendly way to achieve this directly in GUI.

thanks
