nice, but why 500mb installed?
does it provide or count both versions, 32/64, like i read on other app?
it seems 10, 20 times any pdf viewer.
i try to use again such app, as hope to reverse the font and background color.
no idea if you can do it in such app or pdf viewer.
white or green font on black would suite me most.
is this possible any way?
ps.
the actual update has only little improvements.

i help were i can. maybe you can help me too. threads in account/track.
if you don't want to help don't post crap!

It didn't "double in size". It's currently 569MB installed. A year ago it was 460MB installed with version 7.9.0. So, please stop being hyperbolic and making stuff up to try to make a point.

It's 64-bit only as stated on the app download page.

This isn't a PDF viewer. This a is a full suite of ebook management, organization, and conversion tools. If you need a PDF viewer, use a different app.

As for your other questions, please check with the publisher.

Sometimes, the impossible can become possible, if you're awesome!

i meant the diff between download and installed. so it will be the shrink.
not sure which of the both, in first place to schange the colors like invert or customize.
kinda like dark theme but for ebooks on pc or pdf books.
is this possible as of your knowledge?
thx
