People have made some ineresting points here.
I think that it's a good idea to ask what devices member have, because we do get posts from new members asking, 'How do I do X?' And the answer may very, depending on their device. Members don't always think to mention which device they possess.
A drop-down menu, including 'just looking' sounds very promising at first. Then you start looking at all the new Hanlin clones, the older pda's etc, and realise that it would be a very long menu indeed.
So, it's not as easy to fix as one might hope. But it's certainly worth thinking whether an improvement is possible.
