Texpad 1.2.2 is now available in the App Store. This version adds support for the -shell-escape command line option, also it works with unicode throughout, so any characters occurring in your \section commands will appear in the outline view. The demo has been updated to version 1.2.1. Please note that whilst -shell-escape is necessary for some packages it does introduce a security hole. Only use it with packages you trust.
Fixes and features are of course being collected up for the 1.2.2 release. It will improve upon a few aspects of BibTeX parsing and syntax highlighting as well as supporting autofill for \eqref in the same manner as for \ref and \cite.
