Expand the concept of collapsible front matter

The collapsible frontmatter that directly displays tags is one of the features that allowed me to reduce my space-lua functions, something I really appreciated.
I used to have a function that read the page and displayed the tags as "Top widgets."

Expanding on this concept, would it be possible to display the values of other existing "attributes" within the collapsed frontmatter as well, and remove the "x frontmatter lines hidden" text?

For example, if my frontmatter includes:

title: Proposta di modifica
date: 2026-08-08
tags: [SilverBullet, proposta]
status: thinking
myname: Marco
description: Una proposta di modifica.
reference: [[myidea/frontmatter]]

I think of a CONFIG option to define the "frontmatter card display," for example:

# ${title}
_${description}_
${tags}

rendered in the collapsed frontmatter as:

Proposta di modifica

Una proposta di modifica.
#SilverBullet, #proposta

ignoring attributes that are not “cited” and omitting them if the attribute is not present in the frontmatter.

For example, if the frontmatter on another page lacks the title attribute:

date: 2026-08-08
tags: [SilverBullet, proposal]
status: thinking
myname: Marco
reference: [[myidea/frontmatter]]
description: A proposal for a change.

the rendered collapsed frontmatter will be:

A proposal for a change.
#SilverBullet, #proposal

Ok, so basically you want to be able to make the frontmatter rendering a custom widget, yes? That would basically generalize the specific thing I did now. That would make sense.

Yes is correct.
