Jonathan Conti-Vock updated NIFI-9787:
--------------------------------------
Description:
The particular concern this ticket addresses is to make it easier to identify
which row is selected/highlighted after adding a new Controller Service to your
configuration. This change would also make it easier to identify which row is
selected when navigating a table with the keyboard, and fulfill the WCAG 2.1
success criteria "[Ensuring that additional visual cues are available when text
color differences are used to convey
information|https://www.w3.org/WAI/WCAG21/Techniques/general/G182]";.
As you can see below, it is nearly or actually impossible for users with color
contrast insensitivity (particularly a complete lack of color vision) to
distinguish which row is currently highlighted.
