re. the color changes, it is something that we have thought about, worth raising an issue for as there is a solution out there for colouring in the description. Looks like the command name colour itself is a bit of a hack so unlikely to go down that route.

re. the general output, again this should be addressed in an issue, the purpose of this PR is simply to show the available commands in the same format as we currently show installed ones.
