I really don't care for this change at all. The whole business of having to type in keywords to change the icon makes it difficult because I don't remember the keywords off the top of my head. My keywords are long and contain maker names. So, essentially, I won't be able to change the icon in a reply easily at all.

It'd be nice to have an opt out so people could continue to use it as always.

Sorry, but this is a lousy change. Not all of us use mobile devices, you know.
