channel-box-plus will add search-ability over its attributes, and it will colour user defined attributes, making them easier to distinguish. With the threshold argument you can determine when to switch between colours, the higher the threshold the more the 2 attributes will have to match up to stay the same colour, this value can be adjusted using the colour settings that are added to the native channel box menu.

In Maya 2022 and above the layout of the channel box is different which breaks the table views when adding the search widget. For this reason it is omitted for Maya 2022.
