There is a new version of fmWorkMate on the downloads page, with some nice goodies in the fmCheckMate tool.
I'm working on a huge conversion task at the moment; porting FileMaker 12 stuff back onto old FM 11 versions, which means that the focus of this release is on improving the pace of the work flow, that means
useful keyboard shortcuts and
more intuitive flow through the data.
Both the XSLT Chooser and the Text Result Viewer have been honed into efficient tools:
Text Result Viewer
The text statistics really help to find problem characters in your code - or even in any text: just paste it in the text viewer and press command-8.
