My subscription is up for renewal. I'll probably renew, but it is killing me that there's still no full text search (single search box, find all strings across all fields). Instead of doing search in the online app I do it in ToDo.app (has full text) and then search online by the title strings.
I have about 600 tasks, so maybe I need this a bit more than most.
I realize this is probably hard to do with your storage architecture, but any chance we'll see this in 2012?
