1 - When scrolling horizontally on a timeline we cannot see the name of the Item/card. This is really bad for timeline visualization, as pointed in the screenshot.
2 - Make the width of the lines smaller, so it's possible to add more information and occupy less space in the timeline view.
3 - Add a zoom feature that allow you to zoom in and zoom out of a timeline view, without impacting the filter (week, 2 weeks, month, quarter, year)
