First, that's not what I was suggesting. I was disagreeing with adding a winecfg cpl applet. Second, I'm likening winecfg to a very poorly-designed control panel. There are several categories that can go into their own cpl applet, like 'Sound' and 'Graphics' (or whatever you want to call them), though there's not a 1-to-1 correspondence between winecfg tabs and potentially beneficial cpl applets.
Ah, I see now. Well, that's what I'm ultimately hoping to do, although as mentioned before, working out issues with the likes of how to integrate an interface for application-versus-global settings for each applet will require a bit of thinking. In addition, I imagine splitting up/redesigning winecfg is something that may involve a bit of resistance from those already accustomed to its present manner of working. This patch is just the first part of a submission to create a basic control panel skeleton - as I said before, I am hoping to redesign parts of winecfg and shift those parts into their own control panel applets (which technically can be all part of this same .cpl file). For the bits that don't get moved into separate applets, I don't see why a general Wine Configuration icon would be a bad thing, for the time being at least.
