In the meantime there are a couple of things you can do in 1.0 to achieve similar results. Instead of quitting Pleco application, click the on/off switch on your phone. That keeps the application open but stopped. That way the timer, for example does not keep running and when you switch phone back on you will be at the last card you worked on. I am not sure this works with all phones, but does with my current and last phone.
You can also set up repitition spacing. That way it would break up your cards into multiple stacks. When you quit, you would always start back at card 1 but as you get that card right it would move up in rank and go into another stack. That way your stack of 700 cards would soon be made up of smaller more manageable daily stacks and you would work most often on the cards you have the most trouble with.
