hey, why don't you also make the autoupdate of the script so that we no need to update the script manually when there a new version is released? from what i see the plugin installer that available in QC V6 is a great improvement, it is so impressive. and i think this is the version that is worthy enough to buy. and also i think the basketbox plugin that available on the left menu is not a good idea, i think it is better if you make it like this site made http://grosirbajukoreamurah.com (this is not my site, just see the "cart" ignore the product :P). i think this one is great, because it didn't consume a lot of space,i want the plugin function but don't want it to consume too much site space. there is already a number of plugin i cancel to install because of this space matter. that's all of my suggestion. Thank You, Keep improve open solution :)
