I just installed eSword X on my Mac (OS X Yosemite) and the modules directly provided within the Mac app work well
There are many modules at BibleSupport.com that are available for other platforms (Windows, iOS, etc.)
Currently, it appears that a person has to select a module to see what platform is compatible with that module
This requires launching each page only to discover that many are not compatible with eSword X
It would be helpful if the ones that can be uploaded into eSword X (Mac) were easily identifiable.
