The last +3 months I'm missing alot of tools and addresses that are on my main system because I'm on a borrowed laptop, and in no condition to sit at the desk where the main system is located, so I can not make screenshots (printsreen is not working on this laptop)
All I can do is rephrase:
In the menubar with UPI2DB switched on (Posts: New • U (0) • M (0) • P (0)), if there are new messages you click the link and go to the list... then at the right side there is a MARK column.
It's empty and useless because there is no checkbox and no function to mark as read for example.
I hope this clears it up for you Limun
