#13 Allow User to Specify Order of Feeds

[lightforce]

As an alternative to the current method for ordering
feeds (most recently edited feeds shown first, if I
remember correctly), the user could specify the order
of the feeds, such as Slashdot first, EFF second,
Locker Gnome third, etc.

Don't get rid of the current method, as some people
may prefer it, but maybe a "user-specified" mode
could be implemented.

Looking forward to the next release!
