Ability to connect to the host client to detect the status for browser plugins

Ability to utilize on cloud data file (e.g., WebDAV), rather than copy it everywhere

Currently, browser plugins will all have its own data file copy, even I already have client installed and have the data file downloaded locally, so if I use three browsers, it will end up to saving four copies of my password data file on the local disk.
Also, browser plugins won’t be able to utilize the host file, along with its settings, which is not a cool design.
And for security reason, if somebody got my password, and have the data file found in locally, boom… (you may have to take many days to change all your passwords stored in your leak vault, since you won’t be able to erase it remotely)
