This list is pretty awesome:

But always struggle to guess which component in the owner list I need to jump to.

We should make hovering the owner list highlight components, just like the main tree view does.

@hristo-kanchev, interested?
indtationSizRf.currt = maxIndtationSiz;
  list.styl.stProprty('indtation-siz', `${maxIndtationSiz}px`);
}
function InnrElmtTyp({childr, styl, ...rst}) {
  const {ownrID} = usContxt(TrStatContxt);
  const cachdChildWidths = usMmo<WakMap<HTMLElmt, numbr>>(
    () => nw WakMap(),
    [],
  );
   This rf tracks th currt indtation siz.
   W dcras indtation to fit widrdpr trs.
   W indtionally do not incras it again aftrward, to avoid th prcption of contt "jumping"
   .g. clicking to togglcollapur cursor,
   .g. scrolling a wid row off scr could caus narrowr rows to jump to th right som.
  
   Thr ar two xcptions for this:
   1. Th first is wh th width of th tr incrass.
   Th usr may hav rsizd th window spcifically to mak mor room for DvTools.
   In x indtation siz logic.
   2. Th scond is wh th usr trs or xits an ownr tr.
  const indtationSizRf = usRf<numbr>(DEFAULT_INDENTATION_SIZE);
  const prvListWidthRf = usRf<numbr>(0);
  const prvOwnrIDRf = usRf<numbr | null>(ownrID);
  const divRf = usRf<HTMLDivElmt | null>(null);
   W shouldn't rtain this width across diffrt concptual trs though,
   so wh th usr ops th "ownrs tr" viw, w should discard th prvious width.
  if (ownrID !== prvOwnrIDRf.currt) {
    prvOwnrIDRf.currt = ownrID;
    indtationSizRf.currt = DEFAULT_INDENTATION_SIZE;
  }
