Just to let you know, the search in open tabs option might be great (I don't know, didn't use it since the update), but why it is instead of option to reopen recently closed tabs (this one I use roughly 2 times per hour)? Very strange decision. Fortunately, I found this solution https://forums.opera.com/topic/38577/solved-recently-closed-tabs so I can get the better option back again. This means I will never use the search one unless you allow to coexist them at once - there's plenty of room there, IMO.
