It would be useful to have the field option "environment variables", in job's configuration upper in the page and make sure this environment variables are enabled/parsed immediatly after parameters, so they can be used all over the build's configuration.

I've found out that if I want to use a variable in some option fields in job's configuration, such as in Workspace option or "Clearcase Viewname" (using clearcase plugin), I have to create and specify a parameter value because specifying such variable in this new field "environment variables" doesn't get parsed/translated into the actual value, before option I want to use.
I think it's because that every option/field in a job's configuration get's analized/parsed starting from the beginning.

So I think this field should be one of the top options to exist in the configuration, so we can make use of the variables specified.

Thanks in advance.
