Saving Favourite Sites/Wish List

Apologies in advance if this has covered/answered before but I've thought recently it would be nice if there was a section under My Profile where I could save a wishlist of favourite/interesting sites etc.

When I have nothing else I should be doing, (or sometimes because I have something else I should be doing), I'll be looking on here at CC/CL sites around the UK that look appealing/tick all our boxes etc but then move on and lose them so to speak. Yes, I could write them down, mark them in the site directory etc, but just thought a little flag/icon against each site where you could mark and save them for future reference/booking etc might be handy.

I'm not a PC techy so it may not be as easy as all that, but you often see it on retail websites.

Just a thought...
