I would like to open two PDF files at the same time. However, it seems like "doing more than one thing at once" is a concept which has yet to be invented in the tablet world. Is there a way to do it?
Ideally I'd like some sort of MDI interface where I can view files side-by-side. The next best thing (option 2) is a tabbed interface where I can see the files one at a time but switch between them. The next after that (option 3) would simply be to have two files open but use the app switcher to jump back and forth between them.
At first I thought that I'd be able to use Firefox as a container and could make option 3 work - but Adobe don't seem to have released their NSAPI plug-in for Android. So files are opened in their standalone "Reader" app.
The next failed idea was to use Firefox and PDF.js. This actually works, but PDF.js is so ridiculously slow that this is not a viable option.
Then I heard about "Dolphin" which supposedly has a PDF plugin, but after trying the browser out, before even getting to the stage of downloading the plugin, it's clear that this app is buggy and useless.
Frankly, I'm not in love with the idea of using a web browser for this task anyway.
The other idea is to install several different reader apps, but this is a horrible, ugly solution, and I assume I'll have to either pay up or accept ads.
Are there any simple ideas that I've missed? Is there some way to get "Reader" to not close the current file when I want to open another PDF?
