Cool feature from other CI system is to have ability to set dependencies between jobs in a plan.
While we have stages but we need more fine control like in a example

we have build jobs which does't have any dependencies
we have several tests jobs which should be run right after build is available
also for subset of test tasks we gather code coverage we need to run code coverage reported job right after all results for the tests are available.
Also we have checkstyle jobs which doesn't depends on anything.

See attached picture.
We can't achieve this with stages and for CC report task we have to wait while all tests jobs have been finished
