[Loadstone] A small suggestion

Interesting idea for the exploration mode but it just isn't going to happen 
for a few reasons. List boxes seem to be limited in the number of characters 
per item. The docs don't seem to say exactly what that limit is but it's 
quite short, maybe 30 characters if we're lucky. A point name can be up to 
75 characters, then add in the distance and the checked status and you're 
getting close to 100 characters per item. The other reason that the list and 
the first letter search won't work is speed. On a very small database this 
would probably work but it wouldn't scale at all. On a large database a 
search may return a lot of results and take a very long time to do it. Maybe 
on a newer phone the time might be workable but I doubt it. As it is now 
text searches take a long time even on my n70. and that's one of the fastest 
phones I know of.
There's probably going to be changes to the exploration mode but I haven't 
figured out what they're going to be yet. I want to improve things but not 
lose any existing functionallity.
