I also find the sidebars extremely limiting on my Kindle; I shudder to think how little text space would be left on my phone by the time I got the text large enough for my eyes. LOL
I still don't see that Evil Smiley emoticon..... I've seen it on other SMF forums in the past, though, I'm sure of it, so I hope it's out there someplace.
Also, if there is or can be the ability to unsubscribe to threads we've posted in without manually deleting each and every one of our posts in it, that would be great. Sometimes threads take turns OT and I lose interest in them, but I keep getting notifications.
