SMS Blast Function / SMS Quality Improvement
Accounts using SMS with 100s of contacts bring the r! web app down to a turtle's pace.
Particularly when the "pen and paper" icon is selected creating a second instance of the R! web's 'contacts list'.
Removing the slow down of populating the entire contact list again is recommended.
Additionally, an SMS blast feature is desired to send multiple clients the same SMS message.

It appears that when users with hundreds of contacts use SMS on the R! web app and select the "pen and paper" icon, which creates a second instance of the contacts list, the app's performance slows down significantly. To address this issue, it is recommended to eliminate the slowdown caused by populating the entire contact list again.
