Thank you for contacting us. Just to be sure we're on the same page, the left panel should show five filters just under the "Add Items" button. Those five filters are: "All Items", "Recents", "Logins", "Credit Cards" and "Secure Notes". You're seeing all five of those, correct?
Regarding your feature request, at this time, you cannot change the type of filter you see at the top. That is something we have on our radar for a future release, but it's not possible at this time.
The left panel shows two "types," Credit Cards and Secure Notes. I would like to show at least two more in that panel, ones that I use all the time: ID and Bank Accounts, which are currently only shown in the "OTHER TYPES" category. Those are not "other." They are my main categories. Can I add them to that panel?
