I was able to get most of the sidepane working. The only thing I have left is the custom fields and the bottom dates and attachment stuff. I used an array of a data struct which is used to store the fields that need to be displayed. This way I can separate the UI from the Vault UI code and the Vault. The VaultUI just bridges the Vault and UI code. I think it looks good so far, and I even added a nice glow effect when you reveal a password or item.
