I'd love to see a way to delete ALL the mistakes in a past recording. The reason why this is helpful : Once I've done several sessions, the old mistakes do not matter anymore. But I've to go back and manually delete each mistake one at a time, and sometimes there are 100s and 100s of mistakes! This is time consuming, and even though the information itself is beneficial, there's no actual use for past mistakes as we memorise for hours and hours at at time.
