Perhaps I'll add some code to automatically remove the trailing slash. Thanks for the feedback.

[Edit] Done in 1.7.0

Yes it will.
Target release date: mid-december.

[Edit] 1.7.0 released !

No, not without a lot of work to remove the internal HTTP server, remove the internal database (and have Ubooquity use a datasource provided by Tomcat), remove the GUI, add a lot of configuration, etc.

It would be another project in itself and with an even more limited audience as installing and running Tomcat servers is not something everybody can do.

I have not seen this issue myself but I don't own a NAS.
Any additional info/ideas are welcome as for know I don't see where the problem could come from.

An Android client would indeed be easier to use, but would also take much too long to develop (not talking about iOS, I do not have any Apple related skill), so it's very unlikely to happen.

One easier solution (perhaps something I'll do at some point) would be to have a smarthpone specific interface. It's true that the current interface is not really tailord for small screens as I had tablets in mind when designing Ubooquity, not smartphones, which I never really considered a suitable reading device (although I know a lot of people do).

Closer to us, the next version of Ubooquity (1.7.0) will add OPDS support for books and comics, allowing you to use any OPDS client (Android or iOS) to browse your collection. Not as good as a real native client but it should make browsing easier.

The target date is mid-december, stay tuned !
