Description of problem: Sometimes one wants to do a package build only for one or two particular chroots. If a Copr project has many chroots configured it is a bit tedious each time to have to uncheck all the other chroots on the New Build page. It would be nice to have a "toggle all chroots" checkbox to handle this quickly.
Fixed by github.com/fedora-copr/copr/commit/7f9dbdcd. Thank you!
Package including this fix has been deployed on production instance of Copr.
