Search Comments and Change Comment Notification Types

Hello, We would like to be able to search comments. Right now, you can only click the Next and Previous buttons. When there are 100's of comments on a report, this is burdensome to find the ones you are looking for. Also, it would be nice to have notifications like the mobile version on browser. Currently everyone gets the comment notification for any comment input. When there are 100+ people viewing a report and not everyone needs to see the comment notification, it creates a lot of noise. Finally, making email notifications optional would be nice. Our goal is to completely remove email with use of comments (similar to a facebook feed for the work we are doing).
