Icon to end session

Hi everyone,
I love WinSCP and just updated to the latest version, however I notice that there is no more [X] amongst the icons at the top of the right hand panel of the WinSCP screen to close the program. I know I can use F10 but the [X] used to be very handy. Could you tell me how I can add it, (if it is possible)?
Merry Christmas to everyone

Note that there's now "close tab" button (X) on all session tabs.

I don't have an "X" on the tab in either of the left or right panels.
The only X I can see anywhere is a red X and that is to delete a folder.
The tabs themselves only show the name of the server I am connected to.

The X close button does not show on unthemed systems like yours.
Though I was wrong before. The Close session toolbar button was not removed. It is still part of the Session toolbar. You have that toolbar hidden.

Ah THERE it is!! Thankyou so much. I don't like fancy screens which I wasn't using any special theme, just my plain old-fashioned one.
Thank you again. Yayyyy! I have my X close session back again!
Merry Christmas.
