Previous application considered abandoned, now have significant improvements.

[PPage]

Previous utility non-provisional patent application is considered abandoned due to not correcting errors in first filing.  I now have significant improvements to the invention, and would like to file further applications. How does having made significant improvements affect the previous abandonment?

You would have to file this as a new (stand alone) application.  The main challenge here is that your old patent can be used as "prior art" to reject your new version.  If you are only changing minor things like the color or the dimensions that will not be approved but if you are adding in new components or new functionality that may have a chance of being approved as a new patent.
