Hi Hans,

First and foremost: Thank you for uploading the Beta! This solves the problem I have reported with \reference and focus=standard:

well, i have been quite active in implementing what pdf provided and

I agree with you and Pablo: the ISO standard is what counts. And I believe that named destinations, their use, and viewer behavior is described there clearly. 

... so one handicap for me is that i won't make test docs for it
 
I will try to provide minimal examples that I believe are so common that the viewer behavior should be clear.

that one still has to make sure that there is a reasonable view area (so
that one sees what went and comes) ... i'm not sure how you handle it
but esp jumping from page to page in a fit width mode is quite annoying;
fit width actually makes sense when one makes each chapter (or section)
into one long page and i actually played with it but i found no viewer
capable to keep the same scale each page
 
I believe that many people have to make compromises, e.g., cannot afford the time or money to produce both a screen version and a print version of a document. I believe that the fit-width mode is a good compromise - as long as it is viewed in "continuous" viewing mode.

small few page examples with predictable positioning and predictable
spacing (btw, footnotes will always be sort of a pain as they are
rendered in special ways, but footnotes should be forbidden anyway; if a doc is also for screen endnotes are way better)

I agree with you about footnotes. And, as mentioned above, I will try to come up with decent example documents. There are still cases in my documents that don't work and i will try to minimize these.

Thanks again for your effort!
