Consistent use of Builder emblem
Builder currently has an emblem (consisting of a symbolic icon on a background) in use on Matrix. This emblem however is very low quality and does not match the app icon colors of builder. Next to that, it would be consistent to use the same emblem on both Matrix and GitLab. It would be nice to see a good quality emblem for Builder that is used on both Matrix and GitLab. See Initiatives#36 for more info.
Below are some examples of how an emblem could look like. When in use, they will be circular or have rounded corners.
