Planmaker dark mode for sheets

[robert006]

Hi,
I am using Softmaker Office 2004 on Windows 10, in which the dark mode has been selected in Windows settings.
Textmaker and Presentations work areas are black.
However Planmaker sheets are white and I would prefer them to be always black.
I have looked everywhere in Options, User Interface etc. (where update dark and light design automatically from the system is checked), and cannot find a way to get dark sheets by default. I cannot see the Dark mode toolbar item under Add/remove buttons either, so am not able to toggle it for a particular worksheet either.
Is there a way to have Planmaker sheets be dark the same as Textmaker documents?
Thanks

This feature is available only in PlanMaker NX.

There, you can use the ribbon command Dark document in the Quick access toolbar to switch the worksheets from their usual white to a dark display.
