Search Completed Builds by Date Range
It would be useful to have the ability to search through completed builds according to a date range in order to better diagnose build issues that have spawned multiple failures (eg. finding out when an issue originated). If this ability exists, it's not evident.
I could imagine this being useful both in the web UI and via the API (eg. adding a data range param to https://circleci.com/docs/api/#recent-builds-for-a-single-project)
