ZOHO writer's sidebar is in hidden position by default, how to get back to extended sidebar at all times ? thanky you.

Dear community,
since today 16 July the sidebar, ( the one with the list of my writer documents available) is hidden by default.
I can only open it by pressing the dropout button and then it jumps out to the right.
My problem is that in that case the bar covers the part of the document.

I remember a week ago a side bar used to be a constant part of a writer window, as it still is in zoho sheet ( see attached picture).

Due to the reason that i often have to jump between tenth of the documents I need this side bar to be opened all the time,
As in Zoho sheet for examle.

thanks for everyones help in advance,

Andruha.
