Thank you for the great app. I found that I can edit the capabilities (Sign  Encrypt  ...) of my key using your app. I needed to add ""Encrypt"" capability to my primary key  but no other software had this feature. But the problem is that when I change the ""Usage"" to ""Sign and Encrypt""  save  export  and then import the key to GPG  it shows that while the ""Encrypt"" is added  the ""Authenticate"" capability is cleared out! If you could fix this problem it'd be great. I propose you change the dropdown list to checkboxes for ""Encrypt""  ""Sign""  and ""Authenticate""  so any user could choose their desired capability. Also  it shows my ""Encrypt only"" subkeys as ""Sign only""! It seems that there's a problem there too. Thank you again for the great app.
