I've been using 1PW on Mac and PC for some time now and need to organize my stuff better. When you open the 1PW application, the left pane (name?) shows the vault and folders. There is some suggestions in the help and FAQ on what might be entered as a vault type of: Login, Account, Identity, Note, Software, or Wallet. However, more description is needed.
I see that if you click + you get a pop-up type list that 1PW assumes is appropriate for that vault type. The biggest thing that is missing is a description of how the Vault Types and Folders in the left pane of the 1PW application window maps to the Browser 1PW button. On Safari, it appears that there is a drop down menu that shows Credit Cards (from the Wallet) however, not all wallet items appear (like for instance a social security or passport number). The browser button drop down also shows identities which appears to be limited to people type. The browser drop down also allows you to "go to the site" by looking at the folder list. However, not all folders or the items in it appear in the folder list. It sort of looks like the only Vault categories you can get to from the browser are Credit Cards, Identities (people), and Logins via either auto recognition of the web URL or through the "go & fill" option.
Maybe these limitations, interactions, dependencies, and behaviors are the intended mode of use for 1PW but it would be nice to have a better explanation of how it does and is intended to work.
