I don’t know if this question has been asked before.
Or if I have missed a setting (I’m using web-version (chrome) on an Android phone)
For me it would be great to have the opportunity to choose which collections to review. For now I can only choose all collections or only one.
For example it’s a bit confusing reviewing collection with idiomatic expression together with grammar, but no problem to review grammar with vocabulary collections.
So I’d like to be able to review all collections together, except for expression collection(s).
