Is there a way to make the scrollbars on text widgets always visible? No matter what style settings I use, the scrollbars disappear unless my cursor is hovering over the window.
Having persistent scrollbar visibility is a basic usability need (See UX recommendations from Nielsen Norman Group https://www.nngroup.com/articles/scrolling-and-scrollbars/). Without this, a web app's usability is quite limited.
On Developer Edition, you can alter the CSS using the overflow scroll property. I don't think there is a solution for this in any other versions.
body {
overflow: scroll; /* Show scrollbars */
}
