Sometimes I feel like the person prioritizing the releases is Rob Ford, as in they are smoking something funny.
As cool as it is to have an Open Platform, some of the basic functionality of BC does not work and is very embarrassing to present the work-arounds to clients. It makes a developer look unprofessional and the project ill-conceived because the promised ability to edit product information in a spreadsheet is not even working correctly.
CSV files should surround text strings with quotes to eliminate any trouble with special characters. Why not have a comma in an attribute name?
Will Adobe even take a comprehensive look at their product and fix the core functionality? Or will they simply continue to release "cool stuff" our clients don't care about?
Here's a tip though: ABANDON EXCEL and use Apache OpenOffice Calc. You get much cleaner data and get to specify your delimiters, encase your strings in quotes, etc. Oh and its free.
