[Bf-cycles] Should the Glass Node only colorize the refractive part?

Yeah, this is definitely the best and most realistic way to get colored 
glass (unless it's been painted on like my storm lamps on the balcony).

The reason why I bring this issue up is:

a) Newbies might create glass/plastic/liquid that shows non-realistic 
behavior.

b) I noticed that the glass shader is misleading even to experienced 
users because it is called glass but does not act like glass.

c) I ran into this issue when doing work for a client and switched to 
the method you mentioned because of that. The problem with absorption is 
that you will never get the color you enter in the color input because 
absorption is doing a "gamma correction" on each channel which means a 
lot of tweaking is required if you want a certain color for your object

Plastic and colored water also don't colorize reflections...
