Nested Smart Components

Something odd happening here,

I have /acute and in that /acute I have /_part.acute which is a smart component with one axis (width) and another master layer.

If I place /acute and not /_part.acute in a glyph, I can still control the axis, but in a weird way with -200 and 200 boundaries that I did not define:

that is how nested components work. You get delta value for the original setting. You can say: Make it 10 Units wider than how it is set in the base glyphs. It only adds to the setting in the original.
It is mostly meant to build more complex settings as radicals for Chinese fonts.

As a followup to a previous post of crashing issue; where I suspected the reason could be Nested Components;
I’d like to ask if there are any limitations in regard to naming paths “Component from Selection” or any nested component?
Naming that may include special characters; punctuations or digits.
And the other thing >> a Suggestion:
I’d like to see a right click menu similar to this:

“Show All Glyphs that Contain this Component”
Currently when you click “Show all glyphs that use this glyph as a component”, it typesets only the initial level of nested component as a total glyph. The following example shows {circu-center}, a component path, which builds a part of the the glyph “a” and “d” and probably many other glyphs.

However if you wish to reveal at once all glyphs that contain a nested component beyond the basic level of composites; such as: /aacute/acircumflex/adieresis/agrave/aring
you first got to refer to the “a” and then “Show all glyphs that use this glyph as a component”
Why is this needed:
When making a change over a certain Compound Path; you’d often like to instantly view consequences on all glyphs that contain this path; namely complex compound glyphs or accumulated components;
According to the above example; clicking “Show All Glyphs that Contain this Component”, is expected to reveal further to the glyph “a” all glyphs that have a nested compound path called {circu-center}

Technically, the other glyphs do not contain the component. But I understand what you mean. I have a look.
