I had a custom search set on 'd', and now an update overrode that with DuckDuckGo. I know I can just pick a new shortcut for my search, but not being able to configure or remove the default searches was already annoying before and now it actually slapped me in the face. I gather there's some js file I could edit to address this but if patches keep doing this kind of thing, it'll get incredibly frustrating. Please allow full search editing even for the defaults.
