VST Version of Reason!
Rewire sucks, you must save twice and open twice. And you must switch windows. A VST Version of Reason would be nice, where the settings are saved with the project and the window is not as big as the whole rewire slave program. And you can have many Reason instances.
The VST Version do not have a Sequencer and no Mixer! You can load the VST Version as VSTi (Instrument) or VST (Effect).
