Version 1.4.2 has just been released.
This closes a potential sql injection security problem from some code that I inherited so if you are using Schema for WordPress please make sure you upgrade.
As always, feedback welcome either through this group or via the plugin website:

P.S. Version 2 is still in the works and promises to be much better but I just found out I am going on an out of town training course so testing will be delayed - sorry.
