I like having the "always save" option enabled when using the extension but, occasionally, I want to quickly summarize something that I don't want added in my knowledge base.

Currently, in that case I have to click "Open card in app" which will open a separate tab and I can delete it from there.

For convenience, I would prefer an "unsave"/"delete" button on the extension card itself (possibly next to where the "Save" button normally is in the top left corner).
