Have thought about this approach, a few skins are using. But it wouldn’t really fit to how plot texts are shown all over the skin. Some of them cannot be made clickable at all, so not sure it would be a good idea to change the behaviour of one of the texts.
But you could check out the skin settings of our skin and change the plot font size under advanced. That way any issues regarding visibility should be solvable. The text will scroll and should give you the ability to read the whole plot text.
Re media flags… We’re following a minimalistic approach for our skin which also means: no image based media flags, but text. Most of the flags visible in your screenshot are shown by our skin in text as well in the bottom left corner.
