Rewritten some things and turned the grids more minimalist

IMHO this is not a general approach and should be divided in "update license" and "more minimalist grids" while latter one never might be in everyone's interest. I see the commits are already separated, just they should go in different PRs too.
Surely it's possible to cherry-pick some commits ...
It's not me repo, I'm not at all involved in development (even I've my own version of it), so it's just my personal opinion.

@DavidBruchmann I understand your recommendation. I have my own version too, what inspired me to bring some modifications to vision of author. Like a reminder of what yet could be realized and simplified these days. The original has years since the last commit, and beyond simple is very useful. I wish he did not stop there.

Glad you answered, seems I've to check my own years-old version for any updates I've to include ;-)
