Improved navigation in Timeline and Calendar

Please, improve navigation in Calendar and Timeline.

In calendar apps (such as Apple Calendar, Google Calendar) I can use horizontal scroll, to scroll weeks, and use zoom to increase\decrease time scale. And also in all calendar apps you could copy todo or calendar events with cmd+c and paste on different days with cmd+v.

In timeline view instead of separate buttons on top like one Year and 5 Years, it would be more intuitive and convenient to use horizontal zoom to increase\decrease scale. This is more intuitive and allows to adjust needed view (like 6 months, 2 years, 10 years) smoothly.

I believe this tweaks would make app more intuitive for people who use calendar apps and gnatt\markwhen tools (and for everyone).
