Is the Unidata web site accessible again?

I forgot to mention one important feature which addresses the concern
you have here.
After loaded the data and created the displays, you can turn off the
PR in the view window by uncheck the Projections > Use Pregressive
Disclosure. Now, it is safe to do all kinds of operation in this view
window, even the RBB.
The purpose of bounding the Projection and resampling data is to allow an
existing bundle to be used in different area. For example, Don's bundle of
boulder
weather can be used to display the weather of Miami esaily.
Ability to move a bundle easily would be great!
I spend way too much time subsetting individual datasets
manually to be the same. And it's tedious to explain how to others.
That is actually much MORE than just "progressive disclosure," so again
the name is not a good fit to the functionality.
I notice that only newly-created displays have movable domains
by this Projections change method. Will that always be true?
Legacy display bundles will never have this property,
and will have to be rebuilt again? Or could some .xml-adjusting sed script
update old bundles to work with the new portable reloading (PR)?
Only for very high res data is the subsampling (stride) to coarsen the fields
really used, I find -- In the long run, as a user I would wish for something
like this --
averages, not pixel striding, when looking at a dataset at coarsened scales.

Some more comments on PR/PD/whatever it is called:
* Somebody should check how it fails near longitude seams. Currently,
one is forbidden to select data across seams, since the selector window
RBB has constraints on it. But the display area is not constrained that way.
It's too much to hope that the longitude seam problem will be fixed,
but it seems like an obvious place to check for a graceful failure mode at
least.
* Somebody should check how this performs in sphere view. And near seams there.
* I still get a lot of error messages when opening old (legacy) bundles with
this 5.0 alpha.
Most involve satellite images it appears, and appear right away, first thing.
Sometimes the satellite clouds then appear anyway, though.
These errors are unreadable to me, and distressing to users not used to
just clicking "OK" a lot to mysterious errors.
Will there be a backward compatibility problem with 5.0?
Is it easy to remove the displays and datasets and have them really be gone?
I may test some of these things myself, but maybe you will also want to.
Good luck!
Got a target date for 5.0 beta or whatever comes next?
How I dream of getting beyond dataset-by-dataset longitude seams.
