The developers really have a great idea here. The biggest problem is that the app does not appear to be built atop Cocoa, or at least they are not using the proper Cocoa text fields for Spelling and Grammar checking. I have a TREMENDOUS number of custom spellings in my dictionary due to my industry and unfortunately I will not be porting all of these spellings back over. It feels as though they are using Mozilla as a foundation for that and that is extremely unfortunate in this case.

If you hear this guys, please strongly reconsider using Cocoa fields for all text editing for deeper Mac OS X integration and much happier customers. I would probably be willing to be a slight amount of money for this app if they fixed that and cleaned up the interface slightly with Cocoa elements.
