Dear Brad, Diego and all Islandora Views addicted,
after some experience with Views as Navigation bar (
here), I completely replaced collection display with Views for this site
ASA.
There are simple Views and a couple of very complex Views: nested, using Slider and Accordion, based on URL query parameters, needing CSS styling and more.
As usual you can find all steps and exports at our dev site
here.
I'm planning to switch to Views our main site
DigiBESS so more Views will be available soon.
