I haven't been here for some time now, so, is the recently closed tabs list gone for good? Flag #search-in-open-tabs is no more in flags, and with new #search-in-closed-tabs I can't get the old button back. If this is the case it is very, very wrong. Old functionality was already there, why don't we have an option to use that instead of search, there is no need to discard it completely (and recently closed list is much more preferred here on blogs comments if I may notice).
This is Opera's uservoice here, and devs should listen, not ignore the feedback, or worse, doing exactly the opposite of what users said about this "feature"...
Anyway, why not give us both with, lets say, right click on that button give us recently closed tabs and left click opens search box? It shouldn't be that hard to do that and everyone's happy.
