Besides search, copy, maybe translating, this selection solution is also about opening link as text into tab (this is very useful). According to me (I defend bubble solution mind), the bubble is a quick solution and should stay like this : I mean that the bubble (with icons preferably) is a quick reading solution, a small graphical solution and more, a set of selected direct-called functions from context menu. Those user-selected functions are these that the user uses the more commonly and that he expected to get them quickest and easily, without reading all the context menu, and without dealing with submenu levels that extensions enjoy to add. The bubble doesn't replace the context menu, I see it only as a pre-contextmenu, a digest. And when functions are easier to get access, you use them more (instead of forgetting it). The bubble divises features from contextmenu which become more and more heavy today : the bubble for the common and quick functions, the context menu for all stuff linked to selection (included also those of the bubble as doubloons) and their settings. I dropped images into this message about the bubble that have a digest from my search engines, and the context menus that has all search engines as icons. Using directly the contextmenu seems to me an heavy and less and less used solution. Preferably, the bubble could be improved still according to users, adding one and only one subbubble level, using only colored icons, tooltips for adding text info for the name of the function but also for dynamic text info like currency converter or quick traduction. Extension should stay into contextmenu but we can make a special icon into the bubble that emulates the click of the extension menus into the contextmenu.
