Please consider adding an ability to edit comments. It is somehow fairly common for me to type a fairly long comment with some details and send it, and then immediately realize there are some typos. Also, there is something in the app UI which makes it prone to send the comment prematurely before I finished typing it. I am not sure what it is but that happens regularly (just happened today again). When that happens the only option is to delete the bad comment and start over. There isn't even a way to copy the comment text (at least not in the app). Please consider improving that.
