I have a couple of suggestions (or maybe just questions):
First, if there is a way to disable the smiley/emoji "shorthand" in your posts, I'm not seeing it, and I kinda need such an option. For instance, if I post something in quotes and parentheses (like "this" ) without a space between the end quote and the end parenthesis, it will look (like "this" ) instead of how it is supposed to look. Adding the space is a rough fix, but it still looks kinda dumb to my editorial mind. I've found a couple of other examples where I had to edit what I wrote to avoid the automatic inclusion of smileys, but I can't remember what they are. Just giving us the option to disable smileys for a post would be helpful.
Secondly, when I'm replying to a post, I see that flag button in front of the word "Reply" and half the time I hit the flag button instead of the balloon button after the word "Reply." It might make more sense to put the Reply button FIRST in line, since it's the most commonly used, and then put the flag button in between the Reply and Like buttons.
It would also be kind of nice to see when there are new responses to a post, even if they are not directly replying to something you said. Sometimes I'd just like to keep up on a conversation that I'm not necessarily personally involved in, but there's no way to see that there are new posts in a thread without actually opening up the thread and seeing if you recognize everything that's already there.
Just my two cents... or six cents total, I guess...
