Just out of interest: why take the 'foreign' .xmls and what is that .rar doing there?
I'll be happy to be corrected on this (there's always something I've not considered it seems
) but looking at it I would have thought that only the default.xbe was actually essential. The small files sizes make the question about whether to install the non-essential stuff irrelvant, you might just as well do it as not.
But what is actually essential?
Some readme.txt and .nfo are important but in many cases don't contain anything important as regards using/installling the upgraded dash. The readmes and .nfos I have for UnleashX just detail the revisions made in the version being used. Interesting but not important to most users I would have thought. Read them by all means but I can't believe they're essential.
Keepng your existing Config.xml will save you time having to redo all your old settings/main skin etc. Any default new settings the upgraded dash allows will be written to it anyway when you've installed or selected it surely?
Not sure about the English.xml either as, I believe, the default language is English anyway.
