Handling sorting:

Sorting is inherited from previous menu level

Two types: Global Sorting and local sorting...
Global sorting:

<SubMenu>
<Sorting Field="Title" />

Sorts all items in the menu

<Sorting Enable="False" />

Disables sorting at that menu level

Global sorting overrrides any local sorting

Default field is "Title" when sorting is enabled

<Sorting Enable="True" />

Use internal tag value <__SortPriority> on all items and perform sorting at loadup time?

RSS Newsfeeds are an XML standard followed by many "blogs" on the net.
These enable an application to fetch headlines and brief descriptions,
along with links to the articles. MXM cannot use the links at the moment,
but it can use the remaining data from the feeds to provide constantly
updating information in your dash or screensaver! How's that for usefulness?

Users will be able to determine their own newsfeeds, and skinners can also
specify newsfeeds. They are handled in several different ways, providing the 
best (hopefully) compromise between managebility and flexibility.

The first concept is that of a "current" newsfeed, channel and item... when
the user defines a group of newsfeeds, the system will update each newsfeed 
at the given interval, and rotate between feeds, channels,and items in the 
sequence defined in the configuration.

In the simplest terms, you could just have one newsfeed, one channel (most are
one channel anyway), with say, 10 items... MXM would use the <RotateItemInterval>
time (in seconds) to cycle the current item available as a string to the skins.
If you added a newsfeed, it's items would follow the first newsfeed's items.

Skinners can use categories, or ignore that altogether. There will also be a 
user-defined perferred category. Feeds that fail to respond, of course, would
simple fail to be displayed.

MXM will ship with some pre-defined newsfeeds and the user should be able to
select by cattegory and such.
