yes.. i agree.. if plugins can be developed by 3rd party and you open something like e-Marketplace.. i think this will empower a lot of dreamweaver's user since more developer will build great plugins that can be use within dreamweaver.
i hope if this work and you could massively improve a lot of DW extension.. don't sell your company to adobe (just like interakt did)... its frustrating... you have your niche here..:D
Waiting for more 'kick-ass' extension...
