I currently use the web app and phone app from http://hn.premii.com/ I just installed HNBuddy, It's equally good. I'll use it for few days before I decide to switch.
What I will miss from Premii app if/when I switch.
By default, Loads article in Text(pocket/readibility) mode instead of actual web page. 90% of the links I click are articles (save for the Show HN )
Integration with pocket to save articles for offline reading.
Ability to choose Navigation position. I place it at the top so i don't see it when scrolling up and reading stuff down/below
Another feature that's missing on all the apps I tried, Ability to share(to pocket) without actually opening/loading the article. As an example, An article PaulG, I want to instantly share/save without actually loading it in the app.
I had planned to integrate Pocket.. I don't know why I forgot about it.
Note though that:
1. There's a built in "reader" equivalent to pocket/readability. I actually open-sourced this module [1]. It uses MercuryApi (the successor of Readability) [2]
2. it's possible to bookmark articles: this action saves them even for offline reading (you have to open/load the articles at least once though).
Concerning your last idea, I find it difficult to integrate it in the current UI without overwhelming it. Maybe if I add an option (as it was suggested in another comment) to choose between a "detailed" and a "dense" list, then I'll think to this feature.
