comment Can QGIS export Geospatial PDF for Avenza PDF map app?
The answer to the above question states that it isn't possible to create geospatial pdfs using QGIS. There is some support for reading/writing them with GDAL, but as I understand QGIS doesn't use GDAL for output in the print composer.

comment Unable to add shapefiles via drag and drop - QGIS 2.4 OSx
QGIS bug report is here (hub.qgis.org/issues/11399) but this appears to be a bug in Qt rather than QGIS specifically (bugreports.qt.io/browse/QTBUG-40449).

comment EPSG code as dynamic text in ArcGIS
Thanks Peter. It looks like this is the answer. It's a shame so much basic functionality is locked up in extensions and licence levels I don't have access too. It's all about the $$$...

comment Rotating geometry to specific angle using pyqgis?
Look at the code in the canvasReleaseEvent function. L203-210 define the affine transformation, L224-243 apply the transformation to each point in the geometry. This is what you'd need. Or, as you say, you can do it using Shapely.

comment Dynamic Text Formatting Tags
You can do this for labels easily using a Python function. However, as far as I am aware there isn't an equivalent for dynamic text.
