I don't think Comixology lets you read everything. Some things you need to buy. Instead, if you really want to explore the comics, I think all SW comics should be on Marvel Unlimited. The only issue is that some SW comics are being published by IDW, and those are on Comixology, but they're more for a younger audience anyway.
