This is how I access the admin page on my Unraid..  I think I had a little trouble getting there when I first installed it also..

Glad to hear it's still alive :D   (long time Comicrack user here)

As a work around for viewing stuff fullscreen, I'm using Kiosk pro plus, which has a lot of options and is working pretty well.. There's a free version and I had to get the paid one to do what I wanted, of course..  but it does the job..

Not sure if this would be helpful..  or if Ubooquity is still being worked on..

Just got an IPad pro yesterday and I'm struggling to find a way to go fullscreen.. Who knew that would be a difficult thing.. I tried that iCab Mobile, but their fullscreen seems to just make the top bar disappear, leaving the rest of the page basically the same size that it was..

Awesome work on this! I've kinda been sitting on Ubooquity and my collection for a real long time, waiting for the ability to set watched status.. I'm so behind on my reading.. This has inspired me to start cleaning up my collection and get back into things again.. Even considering a new 12" Ipad..

Set things up and I'm loving how it all looks.. Just haven't figured out the progress bars yet.. My photoshop skills are super minimal, but I'm gonna try and fill in some of the missing publisher icons that I have and see what other fanciness I can do.

Nice job on this and thanks for making it available :D

*Edit Hitting 'clear cache' on the top right of the Ubooquity page fixed the progress bars not showing up..
