feature request: consider providing configuration for notifications

[Gigas002]

As discussed in #332, some users would like to configure notifications a bit more thoroughly, and notify-rust provides such settings, so it shouldn't be complicated to implement for config.

twe nice to haves in the notification would be if it showed the filename and when clicked on took you to the folder with it selected

That should be doable as well, #283 tried implementing it, after some review and rebasing stuff could be useful. Though it adds minor unsafe block and depends on xdg portal implementation, that looks like the best we can have for now.
