Mnemosyne should allow for multiple .mem files (or any other file it can work with) to be used at the same time whether through the use of multiple windows or tabs! Personally, I think the use of
tabs would be better since you'll have all the subjects you want to study in one window but both should be implemented. This is useful when reviewing for exams as well as studying for two subjects
if you have two tests in the same day.

Hi,

recent versions of mnemosyne allow to disable groups of cards, so that
even a single mem file makes it possible to concentrate on a specific
set.

Notice that having several mem files don't make complete sense: you
only have a single memory, and it's this memory mnemosyne tries to
train...

Closing this bug since it looks mostly obsolete.

Cheers,
