It would be useful to see how many total minutes have been used, as well as how many minutes remain, in a team's monthly allocation so that we can better manage resources.
My suggestion is for this to be on the pipelines page for a project. For example, in the screenshot below (from https://bitbucket.org/lewisb42/ical4-instructor/addon/pipelines/home#!/) the duration column should have a total that reads something like "Used: 9 min, 14 sec; Remaining: 490 min, 46 sec" (assuming my mental math is correct!) based on my 500-minute monthly limit.
The numbers should be calculated based on minutes remaining in the current month/billing-cycle (and not simply be a total-for-all-time).
