I'd like an update too. I switched to another app for 6 months but am moving back to Toodledo. This has always been the biggest problem with the iPad app. I need my saved searches when I do my reviews away from my desk.
I haven't browsed these forums in a long time, but I thought I'd give a check for progress on a saved searches function on the ipad. When I saw there was a big new update (in addition to the hullabaloo surrounding it) all I cared about was "does it have saved searches??" When it didn't, I really didn't care what version I was running, because I use the app so little due to the absence of this feature. I love Toodledo, but if an online/iOS app were to come out with repeating tasks, 2 dates, and saved searches, you'd lose me.
