I have now pretty much finished up any coding, testing, and debugging for r7 and am looking to have it available tomorrow on the project site.
The next release I have planned (v1.1) will bring wpkgExpress up to speed in terms of some of the new features/changes evident in the latest stable version of WPKG (1.1.2 as of this writing). Previously, wpkgExpress v1.0 has only been compatible with WPKG 1.0.x. I am also planning on having the visualization feature incorporated for this next v1.1 release.
Until then of course, if there are any bugs found in v1.0, I will continue producing minor releases so that fixes can get out there as soon as possible. However, for the most part I will be focusing on v1.1.
