two issues with interactive hyperlinks (please comment)

[Pablo Rodriguez <oinos@gmx.es>]

Hans,

I’m afraid there is a regression partially displayed in the following
code:

    \setupinteraction[state=start, focus=standard]
    \enabledirectives[references.border]
    \setupinteractionscreen[option=fit]
    \setupnote[footnote][way=bytext, location=text]
    \starttext
    \completecontent

    \chapter{Main issue}
    Simple steps to reproduce the issue with notes:

    \startitemize[n]
    \item Open the file and keep browsing it fit to width.
    \item Click on link for note 24 (on next page).
    \item Change view to fit to width.
    \item Search for note 24 in footnotes.
    \item Click back to return to main text from anchor 24.
    \item Change view to fit to width.
    \item Search again for the text with footnote 24 referenced.
    \item Keep in mind that in a 15 inch screen the fit to height,
    text is hardly readable.
    \stopitemize

    \page
    \dorecurse{10}{%
        \dorecurse{10}{This is text.%
            \footnote{This is a footnote.}\par}}
    \placefootnotes
    \stoptext

The regression is that \setupinteraction[focus=standard] doesn’t work
with hyperlink in table of contents for chapter in betas from 2016.02.15
10:26.

Beta from 2016.02.08 15:35 adds a link with named destination (/XYZ).
Next beta from 2016.02.15 10:26 adds a link pointing only to the page
(/Fit).

This is the regression.

And I think it is time to discuss an issue with textual links. I know
you don’t like it. I’m sorry, but I think it is an essential feature for
hyperlinks.

[I’d request other users to contribute their experiences with this
issue, please.]

We need that all links in a text file behave the same way to reach
their destination. Page 2 from sample above describes what is wrong
(and crazy to send a PDF document generated this way [at least, not
relaxing to the reader]).

And if \setupinteraction[focus=standard] is used, all link destinations
should be named ones (/XYZ). Of course, I’m not talking about widgets
for presentations. But footnotes, references, linenotes and other
similar links that may appear in a text should behave the same way in
the same document.

Sorry, but some users complained to me about this behavior. I know that
some PDF readers don’t follow this (only mupdf that I’m aware of
[and I opened an issue:
http://bugs.ghostscript.com/show_bug.cgi?id=696442]). SumatraPDF,
Adobe, evince and xpdf implement named destinations.

It is an extremely useful feature and it isn’t reasonable to expect
from users that they have huge screens to read PDF documents generated
with ConTeXt. And in many scenarios, having a screen version (different
from the print version) is not an option. And as explained in the
sample code above, I have only a 15-inch screen.

Would it be possible that the destinations with links in a text all
honored \setupinteraction[focus=standard]?

Many thanks for your excellent work and your help,

Pablo
