Hi Conor,
In Q3 beta the size of the Documents dll is greatly affected by the English spellchecker dictionary. We will extract this dictionary into separate assembly for the final Q3 version and size of this assembly will be reduced to almost a third of its current size. Another tool you may try is Telerik Assembly Minifier to squeeze the assemblies as much as possible:
