Not sure of process/can’t find help – Focus Matrix – Task Manager Review

When I complete a task, it appears I have to delete it rather than marking it as finished. I haven’t found anything in the app that allows me to look up help or contact the developer. Maybe these things are not a big deal for people, but I like to look back and see what I’ve done, maybe on a list or report. Also, I think of deleting as for things I no longer want or need to do.
