CatalogZone and closing Web Parts

[Larry]

Hi There:

I have been playiong around with web parts - I don't understand some of the
design choices behind CatalogZone and closing of web parts.

1) If you close a web part that is *not* in your catalog, how do you get it
back? It seems to be gone forever.

2) Also, the CatalogZone only seems to allow you to add zones, not remove
them. Is this so?

There seems to be an inconsistency in that if a user is in a state of mind
to browse, they should browse, not be able to close their web parts. They
should only be able to close their web parts in the same area they can add
new ones.

I would think the catalog should display a list of the web parts displayed,
plus the parts you can add, so you could check, uncheck boxes.

Thanks.
