how do I post feedback into listings

Feedback is normally left by the buyer and seller after a transaction has been completed to indicate how they each felt about a transaction that they were both involved in.

If you are asking about something else, please give us a bit more information. 

Thanks for taking the time to look and answer, both people. I am interested to hear you find the listings cluttered, it's always helpful to have another view. I can't get rid of the vendio scrolling gallery despite having cancelled the subscription and always try to put as much info as possible, but maybe it's too much. Thanks for the comment.
