Regarding relate sumatra pdf view, theme, UI setting

[Hiepngt]

Hi everyone,
I am using SumatraPDF-3.5.2-64. I tried many settings to change the view to look like the image below.

However, I can only change the background color in the book section, and the 2-page view only fits the width, not the height, of the software, as shown in the image. Also, there are no back or next page buttons.

In this image, you can see that the PDF and bookmark backgrounds are color #F4ECD8.
The book section displays 2 pages and fits with the height and width of the Windows. and include buttons for the previous and next pages.

Anyone who wants to have the setting or a full Sumatra PDF with this setting can share it with me.
Thank you so much.

That was the old (legacy) eBook (flowing) interface of SumatraPDF which can be downloaded from the historic builds, but it is not going to look much like that for PDF as those cannot be handled that way.
By combining canvas colour with a modified theme, you can adjust to similar, but the eBook right left will not be possible.
