First of all, when I lead an .inf, it applies only part of the component removal and feature enabling/disabling in the UI. Afterwards, if I manually correct this for it to resemble the settings as provided by the previously loaded .inf, the end result when applying shows several components not being removed and/or several features not being disabled.
I tried it a couple of times: load a previous session, apply it to a fresh WIM-file and the program will come up with a lastsession.inf with multiple components NOT removed, even though they were explicitly present in the .inf file AND selected in the UI upon loading of that lastsession.inf.
Overall, this makes the program extremely unreliable and not suited for its needs, as with component removal one will always run into problems that require rebuilding an installation with just one or two components less being selected for removal... With this problem, you'll never know what comes out of the process.
you do realize this is a beta, right???? the next beta release fixes this issue.
