When using darkmode, the borders of selected NPE's become blue. For me, this confusing because persistent entities are blue as well. The inside body is not ‘yellow’ enough to clearly see the difference anymore.
My idea is to use a darker border shade for selected entities, instead of changing the colour altogether :-)
Although I've been using Dark Mode since the start and have already gotten used to it. I can see why it would be confusing to some people.
It looks like both Non-Persistent as well as Persistent have the same ‘selected’-state, an extra blue border. Perhaps a complete border-color change is desired for better visibility, like so:
