Make the upvote/downvote links easier to click on an Android browser. Whatever trick the browser UI uses to make regular links easier to click using the touchscreen doesn't seem to work on the image-based links on LW.
Just having a user option to replace the icons at the bottom of a comment with text would achieve that.
I think it'd be a good idea to keep a list of the ways we'd like to see LessWrong improve, sorted by popularity. Ie. email alerts for new responses.
So if you have an idea for how LessWrong could be better, post it in the comments. As people up/downvote, we'll get a sense for what the consensus opinions are.
I think there's a pretty good amount to be gained by improving LessWrong.
Note: I say "ways to improve" instead of "features" because "ways to improve" is more general.
