Feature Requests

Some Epub files have very poor default font and very small default font size, making it difficult to utilize the powerful reading features of Sumatra PDF. I hope that I can use the EbookUI feature provided under version 3.4 to adjust Font Family and Font Size.

After rotating specific pages of a document, allow saving of the document with the rotated pages.

Be able to split the windows vertically to show at least two documents side by side. I know I can create multiple windows but that's not as practical when you have a lot of documents open

Add a simple way to edit PDF bookmarks (outline)

list all the search result and which page

Customization of fonts type and size, as well as page layout for EPUB disappeared in v3.4. Please bring it back.

Using reference decoder.

Compress, merge and split PDFs. Also rearrange pages with drag and drop

Expose cmd-line functionality like mutool ( https://mupdf.com/docs/mutool.html ). Syntax would be SumatraPDF.exe tool <args>
