You guys really know how to treat paying customers.
I don't understand this comment. Jenkins is free software distributed under the MIT license.
If you're referring to my employer's products or services, I recommend you go through CloudBees support and feedback systems for customers. That could help prioritize support for dynamic refresh of components that are important to you.
But this site is the Jenkins project's issue tracker, not CloudBees's.
there was a technical reason for removing the old refresh feature
JENKINS-19828 and linked issues should give you an idea of various problems with auto refresh. While many of these individual problems may have been addressed since, it's not become a better designed solution since JENKINS-484 was filed in 2007.
Same for me, sometimes I don't see updating correctly, or even the job timestam looks odd. I must always refresh twice the page for MultiJobs.
