Drop-down menu text
It was probably a design decision, but I have difficulty remembering what the icons mean in the drop-down menu. Would you consider an option for changing it to text? Could still have the icons on the left of the list. Could also do with an 'add' option in case the little plus sign was missed, from an accessibility point of view. So having hit the menu button from top to bottom:
Add to Speed Dial
Save for later
Find on page
Obviously the list would be longer than the screen on most devices, so would need to scroll, hence why this was probably not done to start with, but I think it would make a useful option.
I think that this isn't necessary. better way is to display everything as symbols in any type of view: Tablet, classic, phone. Opera team what you think about this?
Something that's missing in Opera albeit present in any other Android app is the tooltip that appears when you long-press buttons, perhaps it'd make using the menu easier if this could be implemented there.
