To avoid confusion in the build history it would be nice to use a different icon for build claiming than for "keep this build forever".
Currently you can only see if a build is kept forerver or claimed using the tooltip.
This can be annoying if you have several claimed and kept builds.
OK, this applies only if you keep a failed build forever, but why not, if the error cause shall be kept?
But even if only keeping successful builds, in build history the quick overview of claim / keep is lost.
