Many paid/non-FOSS apps provide more features then AntennaPod, or have better layouts, but AntennaPod is one of the FOSS apps that is close enough to being what I really want, that I use it over the rest.

The one feature missing that I'm really baffled by is the ability to customize how your podcasts page is laid out, so hopefully they get around to it one of these days.

No. Google podcasts is very basic minimalistic app.
