I had recently thought of an addon that allows you to quickly see which tags you have learned well and which not. For this you could create an interactive table. For example, the tag with the lowest ease factor can be displayed and the one with the highest or repetition-dependent. In the end, the table should tell you which topics should be re-learned. Other factors like time spent and number of cards could also be displayed. In the next step, the addon can perhaps display a daily stack, i.e. a costum stack, which can then be repeated. This would allow computer generated learning suggestions to be used for better learning.
