EDS ux feedback

[Peter Schober]

I've had some feedback today from local Typo3 programmers who never
had seen the EDS (or another DS except for the old SWITCH WAYF with
the institution dropdown list) before and they had a couple of issues
in trying to use the EDS. JFYI/FWIW:

* They typed "University" into the input field (which is probably the
  most characters you can type without gaining any real
  differentiation, in our case)

* and wondered why their institution didn't show up. Because
  we set this.alwaysShow=true and this.maxResults < no. of IdPs.

  * Personally I find the UX of a long list of institutions -- when
    setting this.maxResults to a high number -- popping up at the
    first entered character to be worse, esp when typing more
    characters does not seem to change the list at all, in the
    pathological case of "University".

  * No idea whether the alternative suggestion from them -- adding a
    scroll bar to the list when there are more than this.maxResults to
    the dynamic list -- is doable or desirable.

* As returning users they where not aware that they could click on the
  institution's logo or name below the logo to actually select this
  IdP (no sure what they thought is was being displayed for).
  Maybe this is owed to the German translation (which simply states
  "Previous selection", basically) that does not eve have a verb in
  it. I'll change that locally for now.

There were other issues with entities not showing up but these are
more or less well-known and related to language selection and
unexpected i18n. (The EDS will search for entered strings in the
localized version of the mdui data, and if the EDS doesn't guess the
language from the user agent correctly it doesn't find localized
strings. E.g. the EDS in English won't show anything if you're looking
for "Universität" -- unless an institution actually had German strings
in their xml:lang="en" display name.)
Once the EDS can switch i18n based on request headers (sent back via
the DiscoFeed) I hope this is less of an issue.
