Bitwarden is great! Thanks to the developer(s)!
There is only one thing I’m missing: support to lauch external program (like putty.exe) and pass over parameters from bitwarden client (like servername, username, password and ssh-keyfile which is stored in bitwarden).
…like this can be done with KeyPass:
