I -love- these collections of sequences...

...but I find it difficult to appreciate the sequences as a whole. It is
too time-consuming to look at more than a couple. If they are each
presented simply as an A number, I have to perform a keyboard procedure
that, though for one sequence is not so much trouble, for three or more
is prohibitive for appreciating the collection (the list of A numbers
justs sits there staring me in the face).

Is there an easier way for an interested person to deal with such a
list? Currently, for each A number, the simplest way for me to see the
sequence entry is to cut and paste it to the OEIS lookup site, prepended
with "id:". What I would like is simply a URL (one mouse click rather
than click-drag-change_window-paste-return). In coming up with such
lists myself in the past I find that creating the list of just A numbers
is about the same amount of work as coming up with the URL (one is just
a cut-and-paste of the A number from the sequence entry, the other just
a cut-and-paste of the sequence page's URL (or actually even easier on
my mouse fingers, a right-mouse click (and 'Copy link location') on the 
link).

And email itself is great... but even better would be to give such a
list a less transitory web presence by making it into a web page.
Presumably (?) it is intended to be part of the OEIS (a new index entry
or a special new keyword (probably not)) but in the meantime it can be a
work in progress, a special interests web page (at the OEIS or somewhere
personal, it doesn't matter).

So, for the convenience of the reader, how about (in the future) URLs 
instead of just A numbers?
