Sluggish text input in browser UI (Quick Commands,Preferences, Addressbar)
There is an issue with most text input fields in the browser UI on low-end machines: [b]They don't show typed letters immediately, but with a very noticable delay.[/b] While processing the quick commands, searching the preferences or bookmarks/history on the addressbar takes a while, which is fine, everything the user has been typed into a text input box must show up on screen immediately. That's an usability blocker, which shouldn't have been in 1.0 release! It not only makes the browser look sluggish, it actually slows the user down effectively.
