You can easily add your own styles (CSS) to the list table. The following information is taken from the plugin description:
Styling the list
Sticky List ships with a minimal stylesheet that is easy to override. The table has the class of .sticky-list attached to it which can be used to override the default styles. The stylesheet is located in sticky-list/css/sticky-list_styles.css in the plugins main directory. To override a style just copy it from sticky-list_styles.css and paste it in your themes css-file, then modify the style to your liking.
To style the View, Edit, Delete, Post, and Duplicate links you can use these CSS classes:
.sticky-list-view
.sticky-list-edit
.sticky-list-delete
.sticky-list-postlink
.sticky-list-duplicate
You can change the word “edit” to whatever you like by going to the Sticky List settings tab. Se the screenshots section
