How to set Zoho writer's sidebar permanently to an extended position just like it used to be before, or it still is in ZOHO sheet? thank you.

Dear community,
since today 16 July the side bar, ( the one with the list of my writer documents available) is not standartly visible.
I can only open it but pressing the dropout button and then it jumps out to the right.
My problem is that the bar covers the part of the document.

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.

MAy be it is as skin issue? But I never have touched any of the skin options.
thanks for everyones help in advance,

best regards from Hannover.
