When Session sheet is automatically selected on Login dialog (creation of new session, etc.), the Host name box is focused.
Username of the main session is reused for background transfers.
Different set of keepalive settings is used for FTP. FTP now has keepalives enabled by default.

Command Open in PuTTY uses tunnel for current session.

Optional minimization to taskbar notification area (system tray).
When executed as standalone (not installed) for the very first time, an INI file is used by default, if user has write permissions to directory, where WinSCP is executed from.
Taskbar balloons optionally used for notifications when appropriate:
- When inactive session is disconnected.
- When background transfer queue is emptied (except for active session, when queue list is visible).
- When user interaction is required, while WinSCP is minimized.
- When new release is detected.
