When the event header is enabled, the event button will also show whatever how much I scale the timeline. This feature is wonderful. like this:https://www.upload.ee/image/9136291/____20181031131351.png
However when the event header is disabled,the event button will not show enlarge the timeline. This is not convenient. like this:https://www.upload.ee/image/9136295/____20181031131351.png
Can you fix it so that the second situation also can show event button?
