Before Mavericks, I could maximise a window while holding shift key, and the window would always fill up the entire screen without needing any third party tools or changes.
It no longer works in Mavericks, is there a workaround or hidden setting to revert to the old behavior?
This isn't a direct implementation of Siracusa's vision. It is, however, a Finder alternative that looks distinctly spatial in orientation, an the opposite of the file browser direction most other Finder alternatives (and the Finder itself) seem to be going:
Raskin for Mac seems to be the very spirit of the spatial Finder that Siracusa has been calling for. I just downloaded the free trial and am exploring it, but this might be exactly what I've been looking for.
For your second menubar problem, you can unset the last checkbox in Mission Control preferences panel.
To do this: System Preferences > Mission Control. Uncheck the fifth checkbox "Display have separate spaces"

For maximizing windows (and more), I use SizeUp: http://www.irradiatedsoftware.com/sizeup/
This is not the same as full-screen mode which Mark refers to.
