You notice the address bar now searches the bookmarks as well, that was one of my suggestions (I don't think I suggested address bar history, it has been around for years, it was a long time ago to remember). I have over 12K bookmarks, and trying to find web pages through google is frustrating and suggested this. Trying to use bookmark search is also frustrating as it is too simple,. so one feature I wanted to see was more comprehensive search functions in bookmarks and email, even goggling on the page list in bookmarks for some once seen information, but these are the types of features I mentioned, that Opera seems reluctant to incorporate. Just those suggestions are a revolution for a researcher trying to find something they once saw.

The not having to save to backup a email to draft was something I was also onto them, I am pretty sure the discard button as well, but it is placed such that you can (and I have) accidentally pressed it and it wipes the draft and the current compose session.

Here is another suggestion, I suggested they move the tabs window control into the blank space next to the menus, which they did (which maybe a little bit close to the close apps button). But I think I also suggested that it could go into the application bar, if possible. In reality, if windows allowed it, I would prefer to the panels, new tab, and closed icons in the blank space in the menu bare as well (unless there was not enough room, then Opera would default to the current configuration) and the whole lot moved into the application bar, with the title also inserted in smaller text, or at least the tab controls. Would be extreme, unless you use large sized fonts like I do.

About Firefox stealing Operas ideas, they could always patent those features, if they hired the original inventor of the features ;) .

9.50 was probably a major clean up after all the bugs previously reported, 9.51 just was an easy cleanup of a few missed ones that had been reported recently.
