Backend - Records list problem

Btw, is there a possibility to sort/filter by check-in?

Right now there is such an option. Do you need it?

The question is is is really needed to get list of checked out articles before checkin? Or just make checkin for all checkedout without even know how many are those also ok.

a global checkin will also check in articles which are edited at the moment .. that was the reason why a list / sort would make sense (at least in my opinion)
