Hi Owen,
Thank you for responding. I will definitely post the ideas individually. Thanks for your help.
Following are the answers to your questions:
1. The current focus indicator is blue and is barely visible next to or over darker colors. It would be great if it were an adjustable feature that allowed color and line thickness changes. It does not meet WCAG 2.2 standards, and keyboard and low vision users have a difficult time navigating because they can't see where the focus is. Also, being able to adjust the color means that we have the ability to use a wider range of background colors. Here's what it looks like in our app:

2 & 3. There are times when link text is not sufficient to convey the meaning of the link. An example of this would be when the link is from a word in a paragraph, such as:

The music link shown above goes to a page describing the history of the music scene for the area but it would be unreasonable to use the title or description of that page as a link in the sentence. Also, it would be nice to be able to add "opens in new page" so that screen reader users are notified of that. It is not universally appealing to have "opens in new page" in text after every link.
WCAG 2.4.4 link purpose, level A objective is for users to understand what each link will do when clicked on it. A screen reader user would not have any idea that the music link (as announced by the screen reader) would bring them to a page describing the music scene.
I hope this helps clarify.
