I agree..1 to 2 levels of sorting based on area...
I have also been think about other improvements to the todo list.
Example
Name, Rating, Stars, Loction, Area1, Area2
Birch Tree Crack,5.8,****,WI:Devils Lake, East Bluff Rampart, Pedestal Buttress
Say Cheese,5.10a,***,WI:Devils Lake, East Bluff - West of the Quary, Poison Ivy Wall
Lost Face Finger Crack,5.7,****,WI:Devils Lake, West Bluff - West Rampart,Prospect Point Rampart
Enable Filtering by the following would also be nice.
Location (Already Exists)
Area 1 (Appears only after Location is selected)
Area 2 (Appears only after Area 1 is selected)
Type of Climbs: TR, Sport, Trad, Ice, Alpine, Boulder, and etc.
Number of Stars, *,**,***,****
Grade
--Rock: 5.8 to 5.10
--Ice: WI2 to WI4
--Boulder: V4 to V6
and etc.
