One probably needs to consider that progress indicators may be determinate or indeterminate.

As a quick fix for better search within our documentation, we might be able to use an external search provider like https://duckduckgo.com/search_box . You can specify multiple websites to search and some styling options.

As soon as the official highlight effect(s) are defined, they need to be added to the HIG https://invent.kde.org/websites/hig-kde-org/issues/10

@bshah noted that there is prior conceptual work about Plasma on TVs (or in general with only very few inputs) here:

This work is more in detail from an UI/UX perspective and tries to find a solution in defining three layers of interaction. This sounds a bit theoretically, but might be a good concept after all.

The document also provides different mockups on how a TV/HTPC Plasma interface could look like. I believe we are currently not yet at this point and need to define basic concepts first, but they are still good examples and could be helpful later on.
