A lot of things, I'll answer as best I can to your request.
Crap, I just realized my interpretation/reading mistake for the 2) : False alert, sorry
The ePub "& amp" is the one with the 1) element
I want to specify that this ePub was perfectly valid in the 1.4, Sigil authorized me perfectly this character. The 1.5 failed to load this.
The ePub "JSON" contains the element 6) [copyright safe]

For 3) Yes, this is theoretically a UUID, so it's not the best example, but if I wanted to add a custom one (like "internal-editor-version"), I think having to go directly through OPF is brutal.
Maybe add at the end of the list a "custom identifier" entry that when selected allows direct editing of the scheme (possibly through a small dialog window)
(and I speak only about epub2)
The 4) is a bit the same problem [image], you can't edit the "header" of the
Custom element.
Maybe it's my little comfort, but it would be convenient to not have to think « this I can edit here, this not I have to close the window open a file and find the only thing I'm looking for among 40 lines of raw text ».
(also only about epub2)
And sorry I wasn't clear in my first post.
