There is nothing in Ubooquity's design that prevents the use of FQDN.
I created a no-ip.com account to test it today, and it worked (I pointed something like myname.ddns.net to my IP address and accessed it using myname.ddns.net:2202).

I don't know why it is not working on your side.
You can see how many comics were found by Ubooquity on its administration screen.
If you have a "Total comics" over 0, then you should see them.



When you say "blank screen", you mean completely blank ? Or do you see the Ubooquity interface, but without any comics ?
I found the bug ! Ubooquity does indeed send two "Content-Length" headers. Which are always identical, except for files bigger than 2 GB. That's when some browsers (rightfully) complain.

Unfortunately the bug is not that easy to fix (lots of potential side effects). So I'll put in on my todo list but don't expect it to be fixed soon.

Agreed. I'll extend the "Folder exclusion pattern" option so that it allows exclusion of files in addition to folders.
Didn't know this one. I'll try it out (although not for reading comics as I read them on iPad).
I have not tried but I doubt it. CSS height management is much trickier than it is for width.
The goos news is that the new comic reader is almost complete and will be part of the next version.
It features "fit to width" and "fit to height" options (as well as an automatic split of double pages).
When you run Ubooquity for the first time, it creates a few folder and files in the directory from which you launched it. Among these directories (cache, logs...) there is the themes directory. That's where you unzip the themes you want to install.

If you have already run Ubooquity but you still have only Ubooquity.jar, then your working directory must be somewhere else. It entirely depends on the way you launch Ubooquity (especially if you use a script to do it).
I never commit on deadline for Ubooquity, but I'd say end of august (september if things go wrong) is possible.
