Re: No! Do Not Want!
The caveat is that I do have some sympathy for those who want to minify JavaScript to lower their visitors' bandwidth usage.
If the app is so large that downloading it each time a user accesses the 'website' (I put website in quotes, because it seems like you aren't accessing a websiite, but a mechanism for downloading code to one's computer) uses significant bandwidth, many it should be made into this thing called a client application, that can be downloaded once and re-used many times?
