The icon to represent video is in the set twice:

Haha. Maybe we could alter camcorder a bit to make it look more like a handheld camcorder instead.

We have 3 variants of camcorder. We have way more variants of video. Therefore, we need to do the following:

• [x] Remove camcorder
• [x] Rename camcorder-box => video-box
• [x] Rename camcorder-off => video-off
• [x] Rename camcorder-box-off => video-box-off
• [ ] Alias video => camcorder
• [ ] Alias video-box => camcorder-box
• [ ] Alias video-off => camcorder-off
• [ ] Alias video-box-off => camcorder-box-off

Agree with this change. Just replace camcorder with another icon.

I don't know if this has to wait for 5.0, we can probably do it in 4.6.xx

Camcorder could be changed to an icon like:
