Can the error messages be moved under the butoon and in red?

Hi, I like the plugin, but its very hard to know what is wrong because the error messages are right at the top and are the same color as everything else.

Can you please advise what can I do to change the message error color.

It's not only for error, but when I first tested the plugin by doing a post, i didn't even realize it send the message because I was expecting the sent message below the button, not right at the top.

So really the placement of the error/status message and color needs to be updated.

Please let me know if you can make this simple change, or how I can do it.
