is it possible to have two eM Client applications open at the same time

is it possible to see a second view of eM client on a second monitor - for example to have one screen to see emails and the other screen to view calendar

No. But it’s a frequently requested feature. Hopefully will be added someday. I agree - it would be nice to have mail and calendar windows open at the same time.

Any progress on adding this?

Unfortunately not, we are currently focusing on features with higher priority.
