Hi, there is already a way to do this using command line options. You can either enter them directly into your launching program, or you can create a .bat file or shortcut that has the launch command and then just run that.
To start hidden in the system tray:
To start minimized to the taskbar:
To impose a starting delay of ## seconds:
So you could make a .bat file in notepad with a single line that looks something like:
C:\Program Files\tixati\tixati.exe -starthiddenintray
and then just point your VPN launcher at the .bat file.
