1 - Change the configs folder in Linux, many people uses Chromium, and SRWare Iron uses the same ~/.config/chromium, change that.
2 - Are there any plans to have another package to install restricted codecs for use in the Iron? Chromium in Linux usually has a separate package that installs all these codecs and enables the use of MP3, AAC, x264 in it.
I think these problems are the more remarkable when one wants to use the Iron.
