No downvote is a known issue, partly because I can't test it, so I'm not confident I'll deliver a reliable feature.
I agree that upvote should be more visible. Currently it's available as an option tucked in popup menu, as well as via swipe gesture, which is not very discoverable.
3rd one is a feature called 'deep link' which is quite common in Android. It should remember your choice if you choose 'Remember my choice'. I don't know what went wrong here as it is a platform feature and out of my control :(
Thanks for checking it out anyway.
I suspect you've got a bug with the deep link feature because other apps only show this menu one time. Yours shows it over and over.
While we're talking, I also found the UI rather busy with stuff that seems unnecessary. Half the fun with HN is its simplicity. If you ever get the urge, think about doing an Apple and removing stuff that people don't use.
Nice work, anyhow, and thanks for that. Consider making a paid version of the app with no differences, except you get some money back from it.
I'm wondering if my post would be enough :p
If you don't have enough score, drop me a mail ;)
That's Android's fault, not the fault of Materialistic. I have the same problem totally random on my phone, too.
First, no downvote action. We need this to push down trolls and sockpuppets.
Second, voting is inside a menu, yet this is a really common action.
Third and worst, when I use a browser on HN, every single link now asks me to select an app. Not once, but for each different link type it seems. After the fifth time (choosing 'Remember my choice' each time), I was so annoyed I uninstalled Materialistic.
End of report.
