Gerd,
The MyEclipse 2017 release will be based on Neon, and should include at least this functionality. 2017 CI 1 should be available in a couple of months.
We are also working on some related features for 2016 as well. Can you tell us what Grunt/Gulp/other capabilities you are most interested in? The ability to run tasks from within the resource explorers or other?
Thank you for asking.
