bar lines for 4 bars in overview timeline

To sync tracks it would be great if one could easily compare how many bars until a drop appear in the overview pane of the song to be able to see how many bars until a specific time point. So in the overview pane of the song there could be a line for every 4 bars (like in Cross DJ) In addition it would be great to analyse/mark the starting point for a sequence of 4 bars. With this, syncing tracks would become much easier. With Cross DJ this is nicely analysed and visible.
