If you’re responding to my points, I don’t know why you’re talking about breadcrumbs. You may have missed it, but in one of my replies to you I said that I’m not interested in them, and I agree with you that they’re not naturally feasible. I’m only talking about other forms of hierarchical representation.
I hear that for you, widget-trees are “in practice not very useful.” Great, I completely support you not using them! I’m telling you that in my practice they’ve been incredibly useful, and I’m not the only one who’s said as much in this discussion. In fact, if that feature were ever removed from AT, I might stop using the app (or at least stop updating it). I don’t believe we can have a good-faith discussion if you can’t accept that that’s true for my use case.
As for being careful what one wishes for, I can’t speak for anyone but myself. But my wish isn’t vague or poorly-thought-out at all. I know exactly what I want: the widget-tree in a different visual form. The logic already exists and is functioning. Other enhancements, like the filtering @Zak-from-Zork suggested, or the upward family-tree-style expansion I showed in my diagrams, would be gravy. I think my successful use of widget-trees for months is sufficient basis to forecast how variations on that functionality could be even more useful for me. Of course I could still be mistaken, but that’s the nature of forecasting. I think I’ve done enough of my homework at this point. And I wouldn’t presume that I’m the only one with a clear head among everyone who’s asked for this sort of thing here or in that FR thread.
One last time, for good measure: I know this sort of feature wouldn’t be good for everyone. Probably especially not for you! I don’t know what percentage of the userbase, current or future, it would actually be good for, and whether that would justify the devs spending their limited resources on it. But that’s their call.
