Added session flow suggestions

@kingToolbox
Dear Authors , I have a few suggestions .
1. Disable input master password when add seesion after connection , Because most users think that they need to enter the server password, I will enter the server password when I use it for the first time, but it is actually the lock screen password. I don't know what the password is when the screen is automatically locked? this is misleading
2. Hope can enter the account password when configuring the session, Instead of clicking the connect input after configuring the session
3. Add support sync seesion authentication data file from cloud disk (Such as: iCloud/Onedirve/Google Drive/Dropbox/NAVER/FTP/Web Dav)

The open source spirit is great, thank you ！

The issue proposes changes to session password entry, lock-screen password wording, and syncing authentication data through cloud services. Start by locating the session configuration and authentication flows, then identify how cloud synchronization is handled. Done means the requested session behavior and supported synchronization options are defined and implemented with appropriate coverage.
