The review progression currently counts down and took me a bit to figure out that it was not counting each review item as its own decrement. Instead seems like characters or words can be represented in multiple review items.
It would be nice if I could see the true amount of review tasks left, for example, 50 sounds doable but in reality this may be 100. Or that I can see a separate counter counting the every single flash card and a counter for the current situation.This allows me to better estimate how much work there is to do.
