@Robert Berendt actually I use it a lot. I found it very useful and easier as HMC, as I already use ACS for 5250 console.
And it comes with a bonus: displaying some code information, just hovering your mouse on them ;)
Please just be aware of the authentication: it uses the user you specified in ACS configuration, when setting up the 5250 Console thing. Can be retrieved somewhere in XMLs after saving ACS configuration.
