Whilst it's currently possible to zoom in/out in the Day\Timeline view, you have to do this manually and it can be very granular so you can end up recording to the second.

I would like to see an option to be able to configure the default view e.g. 5min, 15min interval etc.

This would ease recording and categorising tags for organisations that have rules around minimum billable time, or minimum time recorded intervals e.g. 5 or 15mins particularly when auto-tagging may nto be appropriate

NOTE: workaround for recording time as whole mins can be found in this request "Tagging snapping at 5min"
