I really like Memex shortcuts in the browser extension. One thing that I am really looking forward to finding in a bookmarks extension is to be able to access the bookmarks right away without using the mouse. For example, I would love that when I activate the browser extension window and type something to search, the results will show right there in the same pop-up window and not in a separate memex tab and that I can just use the arrow keys to scroll up or down to select one of the search results. something like the way a tab extension works (e.g. https://chrome.google.com/webstore/detail/tab-switcher/gcilookdakgpccpbcjgnpaecofklimck?hl=en) but with the bookmarks stored in memex.
