Allow developers to see full variable name in custom states. If you have several similarly named items, it is hard to distinguish them quickly.
Also, why not let a user expand width of that panel?
The way this is handled is bizarre.
Sometimes it defaults to ABC order. Sometimes it doesn’t. I have pages with 20 or more custom states and it just makes the process confusing.
If a custom state is applied to an element, show an icon similar to the orange one here that relates to Workflows. Same for comments.
