The compose box is very small and hard to see. I frequently miss mistakes because the text is so small.

A compose box which is bigger, where images attached and general text is larger and more clearly formatted would be a big help. Potentially you could make it less of a compose box and more of a compose page, where suggestions could be added in line with text and it would be easier to visualise what a post will look like.

I think that this feature is essential to making Sendible more user friendly.
