Gosh there are some aspects which I don’t understand. But I think it is OK…
I guess that language (for example tick marks) is part of the issue.   (I was looking for "   ` ").  So if I can get what I need out of the software that is good enough.  I am glad that now I no longer need to go into my text editor to make new power symbols which are similar to existing ones.  Because:
- I think I can make and use power symbols effectively
- Apparently this is legacy which no longer seems well justified
- I think that many of our contributors are in Europe or other places where English is not the first language, and if I had to conduct a discussion in German or Polish I would be completely stuck.
so I will not dig too hard.
I just about had Aliases figured out, and it seems that those are being discontinued in nightlies and Kicad 6.
