New pattern dialog

This was a feature I worked on, before I had a major unrecoverable harddrive crash… stupidly without a backup. It didn’t make it into the app. :frowning:

I will usually post in the Developer CAT and update as I work on (new) features just to keep users / devs informed as to what I’m working on so they can give input if they want. In this case it will also serve as a record of what I did before when I get a chance to pick up the issue again.
