How many "Dreamweaver Extension" have your written?
What would you want in it?
Once you have written it you would have to assume that Cute have a consistent model such that there are no surprises with revisions unless you have the extension just for one version.
Cant see why you would need a Dreamweaver Extension myself, its easier to wrap it up into a function and jkust call that - far easier to manager - unless you are not a programmer and rely on the mindless way that Dreamweaver inserts Inline Code.
You could be right about easy money tho.
