I mainly hoped to motivate others to improve upon it. I'm afraid I haven't really had much time to look at it. That was one year ago already? Wow.

As an aside, while really stupid in principle, reflow actually works tremendously well on a MuPDF-rendered EPUBs.

I do apologize for not at least giving you the following information more explicitly, although at the time I hadn't actually tried it like I did now. As a basic workaround you could mod the PdfDocument file yourself like this:

diff --git a/frontend/document/pdfdocument.lua b/frontend/document/pdfdocument.lua
index 34f072e9..14ae115d 100644
--- a/frontend/document/pdfdocument.lua
+++ b/frontend/document/pdfdocument.lua
@@ -42,6 +42,8 @@ function PdfDocument:init()
     if not ok then
         error(self._document)  -- will contain error message
     end
+    local Screen = Device.screen
+    self._document:layoutDocument(Screen:getWidth(), Screen:getHeight(), 50)
     self.is_open = true
     self.info.has_pages = true
     self.info.configurable = true

In a diff file, + means added lines and - means removed lines.

So basically just add those two lines in that location:

    local Screen = Device.screen
    self._document:layoutDocument(Screen:getWidth(), Screen:getHeight(), 50)

The "50" here is a font size value that you can play around with.

The problem is integrating it properly into the UI, and even purely code-wise that's a just quick hack instead of proper code that can actually go into the program.

But of course perfection is the enemy of progress. Proper code + configuration first, UI later. I can't promise anything though; my spare time may be limited.
