Not being able to delete messages within a conversation without having the long press them and hit delete one at a time.
A lot of times I only want to keep certain parts of a conversation not all the little stuff that's not important that builds up, so
Being able to delete multiple messages within a conversation at one time.
Long press 1 and then it would open up radio buttons to be able to select multiple other messages within and hit delete all at once.
Having to long press every single message and then get the pop-up to delete it is time consuming
