I haven't been that impressed with the contents of Logos Now as of yet, but I can appreciate the idea. As of now I will not renew my subscription when my free month ends. However, with tomorrow's release that might all change!

Lately I have been reading up on the attributes of God and I think a tool on the attributes much like the "Commandments of the Law" would be helpful. It could link to systematic theologies, dictionaries and even sermon excerpts on each attribute.
It could break them down into Communicable and Incommunicable and go from there, listing scripture references for each....
Each systematic breaks them down different so maybe it could sort them by systematic theology and link to each section.
In each attribute there could be a section for notes where we could make notes and or hyperlink to different resources.
These are just a few ideas, maybe others have better....Big possibilities though!
