it's difficult for me to enter e.g. the „Estimated time” in hours. I've to calculate how manny hours are 2 minutes helpdesk …

Also the projekt-time-display is hard to read: 2.80 hours.
maybe there is a way to enter time in 0:05 as 5 minutes and have a output of 2:48 as 2 hours 48 minutes instead of 2.80 hours …
