M-dash, delete used social posts from campaign list, and fix the upload of photo process

1. M-dash: make two dashes merge into and M-dash. The writers who are your clients have been asking for this for years.

2. Let us delete used social posts from campaign list, or give me a reason why we should not. They are wasted space isn the list of campaigns and I want them out of the list. I'm lots of others would too.

3. Fix the upload of photo process. when you upload a photo, there is no "Done" anymore. All you can do to get the window out of way of your work is to hit "Cancel." (That's not confusing!) So you hit "Cancel" and guess what? The photo has been uploaded. Come on guys this is basic.
