What it does: Displays the absolute time spend in the main screen after the Studied X cards after X time. Nice companion to Show total review count on main screen
I restricted the version range because I observed that in Anki 23.X, the add-on was causing errors when there were no reviews in the collection. Someone complained about this issue, particularly for brand new profiles. I will take a look and update it as now I use 23.x myself.
