I do my lessons/reviews every day but on an erratic schedule, so often my mistakes disappear before I can get to them. Could an option be implemented to make them stick around longer than 24hrs?
For me personally I find the recent mistake super useful, like it engages a separate part of my memory/learning.
As a workaround you may use the Failed Last Review table of Item Inspector. This displays a list of the items that has failed their last review in the last X hours where X is
user configurable in the settings.
You may study the failed last review items by reciting the meaning and reading aloud and reveal the answer by moving the mouve over the item. You may also get quizzed on these items by clicking on a button.
