Allow Users to Customize the Color of the Link Set Feature
When using the Link Set feature to link two or more resources, a small orange box appears attached to each linked resource's book cover icon with the letter A - F in the middle of the box. The extreme bright orange color used for this indicator box distracts me from reading the resource's text and causes eye strain to the point where I cannot use this feature.
In view of the above, I suggest any one or combination of the following options:
Option #1. Allow users to individually customize the color, shade, and brightness level of the Link Set indicator box as well as the font color of the letter inside.
Option #2. Change the Link Set indicator box's default appearance to a more neutral, less distracting color (such as grey).
Option #3. Eliminate the box and simply attach the Link Set letter, using black font instead of the current white (or ideally allowing the user to choose the font color).
Option #4. Replace the current Link Set indicator box with a less conspicuous indication that a resource has been made part of a Link Set. This could be accomplished through an additional grey icon along the resource's toolbar or through some type of visual indicator within the resource panel menu.
Regarding Option #4 above, I continue to recommend this option be accomplished through some type of visual indicator/selector within the Resource Panel Menu; however, I no longer recommend adding additional icons to the Resource Toolbar unless that would include a one click option to "hide" the Resource Toolbar if one prefers when operating in a normal panel view (not Reader View) or an option to choose one's own icon.
I've recently come to realize as more features are added to the program, it will invariably clutter the Resource Toolbar with icons, some of which could distract users from reading resource text or performing other functions. This is happening for me right now with the recently added Multiview Resources icon which appears to my eyes to dominate the tool bar and resource text beneath it.
