As the title really, but here is some screenies too go with the question.
These are the IconPackagers that I have presently installed.
This is the one I am using: Next Domain made by Vampothika
Although her icons are from 2015 I would still have thought they be showing within the software itself, especially since the Flash BlackEdition and Flash Live from 2009 and 2008 is showing, as can be seen in the two first screenies ? Now if trying another Icon set and not liking it you have to go back in and reinstall it each time. Not that it takes that long time, but still, think that's a flaw in the system, no ?
On a side not for Admin, if anyone from Stardock Support reading this that is.
On the IconPackager Support FAQ, under the headline What is IconPackager ? and the link after *Documentation can be found here:* the link is leading to IconPackager version 5. Maybe update the documentation to version 10 ??
