#' Enhanced progress with logger message
#' @description For best performance, please install \code{'ravedash'}. This
#' function can replace \code{\link[dipsaus]{progress2}}.
#' @param title,max,...,quiet,session,shiny_auto_close see
#' \code{\link[dipsaus]{progress2}}
#' @param outputId will be used if package \code{'shidashi'} is installed,
#' otherwise will be ignored
#' @param log function, \code{NULL}, or missing; default is missing, which
#' will use \code{logger} function in the package \code{'ravedash'}, or
#' \code{\link[dipsaus]{cat2}} if \code{'ravedash'} is not installed. If
#' \code{log=NULL}, then the message will be suppressed in 'shiny' applications.
#' If a function provided, then the function will be called.
#' @returns A list, see \code{\link[dipsaus]{progress2}}
