For personal use of LastPass it would be most helpful to show the creation date/time and last used data/time for each password. Perhaps make displaying this an Advanced Option for us.
I finally have some free time lately and so I've been going back through my vault to clean things up, remove duplicates, old entries, etc, and it would be so useful to be able to see the last used date so when I find somerandomsite.com and can't even remember what it was for I could at least be able to narrow down when I last used it. Most likely if I can't remember and the site is offline then yeah it's garbage, but it still would be nice.
