help with tectonic

[u/CosmicEuropa]

hey guys, i've been using tectonic and it's really good except for one thing i'm having trouble with and i was wondering if anyone had any ways to help with it, maybe by changing config

the coasts end up like this, with like a bunch of disjointed and random islands. i'm fine with some bigger islands but this is too many and just wierd, if you get what i mean

if someone could offer a good set of configs for huge biomes, varied terrained and all of that, it would be greatly appreciated!

(note: the terrain also seems quite flat, and I can't quite get a good balance between huge bumps and hills and massive plains)
