This has bothered me for a while...
If you go to advanced mode and show hidden that works fine. If you then click on a column to sort the addresses, the show hidden flag clears and you're only shown the sorted list of unhidden addresses.
I can find no way of sorting while showing all of the addresses.
Also, I asked about this previously too:
On the advanced mode tab, you have:
[_________] Search Addresses
Could you change that to:
[_________] Search Addresses ( [x] Search hidden )
Where 'Search hidden' is a preference that is saved in the cookie.
Cheers,
Al
