1. do you have a doc with all your custom codes
I’m sorry I don’t really know what you mean by this?
2. is there anyway to hide the “read more” button on post list, so just have it display the post (if its a short post for example)
You can sort of do this without needing to make any customizations. — When you’re configuring your post list, you want to set it up to show “full content” and NOT “excerpts”. By doing this, it will make it so you have to insert the “more” tag into your posts.
The only drawback here is that the the “Read More” link outputted there will not look like the nicely styled button.
