Displaying events with 5 minute increments

Thanks for this plugin!

My client has events that are scheduled at varying start times – e.g. 10:00, 11:25, 12:30, etc.

I’ve got the timeframe for the timetable block set to the minimum (15 minutes), but this still means that an event running, say 6:25pm – 7:25pm, is displaying in 5 rows (6:15, 6:30, 6:45, 7:00, 7:15). Therefore events of the same duration (1 hour) are showing different sizes, depending on the start time – which is a bit confusing for the user.

Is it possible to add 5 minute and 10 minute increments to the ‘timeframe for event’ parameter? Or are there any other workarounds I could look at?

Many thanks,
Sarah
