Where is my contact list?

From one day to other,the contact list from the right side just disapeard and I’ll go crazy to look for a contact from a list from tools,contacts! I like them on the right column,What can I do?please

Unfortunately, we removed it with the last update because it was underused and we would to make graphic more clear. You can vote for getting it back here: https://discourse.emclient.com/emclient/to…

I’ll give it a bit more time,may be I will get used to contacts not on right side.
I really like the attachment history ,so thank you,I’ll be OK for now
