Is it possible to "highlight" a workflow transition button?

[Adam Humenansky]

We're using Jira Server, and a user raised a question to me today.

Can we highlight a Jira workflow transition button? 

My first thought jumped to "opsbar-sequence" so I reordered the buttons to put them in order of "preference" (i.e., moving the workflow forward instead of backward).

However, while I was editing the transition properties, I had the thought that there may be a property for "button background color" or something similar. Something that could set it apart from the other options, as opposed to just a better ordering of options.

A new thought just came to me based on this question:
Approve could be colored green, and Reject could be colored red. That could be a widely beneficial "use case" based on this idea.

On a side note, when I have both behaviors (select list conversion A trying to update B and vice versa), I noticed I can't edit or create issues.  I looked at the browser console and saw the following JS error pop up a few times:

Uncaught TypeError: Cannot read property 'toLowerCase' of undefined

My guess is that the JS error hoses the edit/create form, which prevents the button from submitting.
