Re: Template question
By default, the BP packaged theme is a child theme that uses the “bp-sn-parent” theme for the homepage, but you can always override it by copy and pasting home.php over to your child theme.
In this case, you would copy home.php from “bp-sn-parent” over to “bp-default” to override it.
If you’re starting from scratch, I would make a copy of the “bp-default” directory, rename the folder and start experimenting.

Hope I didn’t confuse you!
