Thank you for Primal app, it suits me the best. 

But here are the things which annoys me a bit:

1) Let me choose my default list to follow (Primal always switch to latest with replies) 
2) I should always click on the button at the top of the app when new posts appeared, would be nice to have X/Twitter UI here, just show the new posts without the need on clicking any buttons 

 Thanks for the feedback.

1) You can reorder the feeds in Settings->Feeds screen; The first feed is the default one.

2) It used to work like Twitter, but we had some gap issues and this was the compromise we had to make. At some point after v2 release we might revisit the implementation and try to improve it. 

 On point 2)

Would it make more sense on forcing me clicking on HOME button at the bottom? Show me I have new posts at the top and force me to click at the bottom HOME button (or both ways), so it would be almost the same UI as on X, except auto scroll.  

 Asking for this, because on a tablet it's way more convenient to click on bottom buttons.
