Visual Studio and command-line nuget share the set of configured nuget servers (it goes into %appdata%\nuget\nuget.config).

It'd be nice if Linqpad honored this also, rather than having to (re)configure the nuget servers separately which is really boring.

If keeping a separate list is seen to be desirable, what about an 'import from nuget.config' button to bring them in as a once-off?
