I'd also like to request that unique sort orders be able to be saved along with a saved search.
I love ToodleDo, but my task lists are long enough that not having a custom search order is killing me--because as soon as I set the order the way I need it, I go to a different list and have to change that list's sort order to the right way to view tasks in it. And as soon as I do that, I've obliterated the first list's configuration. It's just a real headache when all I really want to do is view my tasks in a certain standard way each time so that I can find the tasks that need to get done.
I would definitely also love to have this feature. I have several different custom searches, which would be much more efficient if they could include custom sorts. As it is right now I night to change the sort manually every time I switch to a different search.
Please put this high up there on the to-do list for implementation. This is the only Toodledo feature that is bothering me which might make me look somewhere else because of the time I spend having to switch the sort order. Otherwise I am loving Toodledo!
