That comment wasn't directed directly at torrent support. I merely listed torrent support as an example of how they add a feature and have yet to expand it. My comment was more aimed towards roboform. You are limited to using the wand or you don't have much of a choice otherwise. Am I wrong in this arena? Can you in fact use roboform or any other form filler/password manager with opera? Yes, keepass works, but that is more something sending keystrokes to the browser, not a true form filler since it cant gather field names to determine what values to fill in each field.
Anyways, when it comes to irc, again, this isn't what my comment was directed at. I don't use email or IRC from opera because they are, in my opinion, substandard, more difficult to use, and don't belong in a browser suite (Mozilla realized this, and as such the Mozilla suite is basically being eliminated).
Your pointing out the spell checkers reinforces my point that a more suitable API or plug-in based system is required so that you don't have to jump through hoops to get features like this to work. I would love to use my auto-complete utility to fill in where opera fails to add a feature (Auto-complete is another highly requested feature, and no, notes isn't an acceptable alternative since I don't want to type every possible auto-complete or web address into a note field). This again, is an example of where a user should be able to grow the browser as their own without having to resort to only what the developers add to the browser.
