Total Commander

Using the SFTP plugin, when editing a file on the remote server, when saving the file, TC copies it in the background and plays a notification sound.
It would be useful to be able to customize that sound like we can customize all the other sounds in TC.

I personally would like to enable the option to only play the sound if copying the file to the server takes more than 10s. Or at the very least be able to play a different sound than the windows default one.

"Configuration" -> "Options..." -> "Misc." -> "Custom sounds" -> "Only play for long operations:" -> ">" set the seconds.

Yes, those settings work for everything but not SFTP plugin for saving files in the background. That is what the feature request is for.
