I cant agree with you more on there “bad choices of fieldnames in the past” but I am confident most of these of these are irreversable.
- I will share later an idea which allows a tiddler to have more than one “tiddler type” at once, as is currently the case of you use tags for this.
- In this case actually the use of the “types” field may be practical.
But it was wrong for type/status/version to be used by the core.
