Either a Screenshare-only add-on, the ability to disable the voice/video options, or restrict initiation to agent-only!
The fact that customers can initiate video and voice functions combined with the fact that you can't disable ANY of the 3 services provided by this add-on makes it ENTIRELY unusable for us. We only want screenshare and would never make use of video and probably never use voice either. Because there is no way to limit this from the customer's perspective, we'll never be able to take advantage of this add-on. We need WAY more control over how this is (or is not) presented to customers...especially when you are charging between $29 and $49 for it! We've been asking for this since the add-on was first in beta. :-(
