when are u going to put the browser option in the right of the toolbar
Not a matter of "when" but "if" they will do it someday. Since Opera always had the options on the left, i don't think they are even thinking about changing it.
and the option to recovery closed tabs?
Omenu > Recent Tabs. If you mean the "trash can" like in Presto, i don't think most uses keep reopening closed tabs so often that worths the efforts to implement it.
