This is not possible with the current version of Ubooquity

But the next version (Ubooquity 3) will allow full control over the html pages with a new theme system, so you will able to translate the text you want.

I will release a beta version this summer.

Thanks !

I'm still working on it whenever I find the time and energy.

Still have some work to wrap up the ongoing modification, but getting there.

I aim at a new release this year.

2023 :)

(hopefully during the first semester, I really want to wrap this version to be able to go back to a more regular release rythm, but we'll see)

Not yet, but the next release will allow finer bookmarks management: you'll be able to mark a book as "unread", resetting the reading position.

No offense taken.
I'd probably do the same thing as a user for any other software. 

There is a bug that prevents the validation of the admin login form with the "enter" key.

So right now I don't think you will be able to navigate using only the keyboard.

The bug is fixed in the source, so it will be part of the next version.

I don't know if this will be enough for a full keyboard navigation though.

The error you pasted in not linked to the admin authentication, it's your browser asking for JavaScript debugging files (it happens when you open your browser console and it has no impact at all).

You can't store the credentials in the preference file, but you can generate the "webadmin.cred" file yourself if you want, with a bit of work:

The metada (in the database) and cover file thumbnails are deleted.

The scan process principle is very simple: Ubooquity lists files to get their path and last modification date (it's very fast as the files are not read, only the disk "table of content" is), then it compares the modification date it stored in its database during the previous scan and processes only the files that have been modified since the previous scan (by "processes", I mean reading the file to extract the cover and metadata, which is the time consuming operation).

So the first scan of a big collection will take a long time, but subsequent scans will be very fast if only a few files have been added.
