- Modified boolean columns to create a collection name the same as the column name including books where column value is True
- Modified default keys in menu (e.g. after opening menu, pressing 'C' runs Create)
- Fixed crash when reporting that the collections file had an incorrect format that was fixed
- Fixed error when trying to create collections from a boolean column
