some Questions about Mask on Line Profiles

Subpath

Due to my experiments with mask on line profiles
I have a few questions
.
.
1
First of all, was my approach right?
Well, it worked

As you may have noticed, I used the role.
"Transparency Content" for the mask on stroke profiles.

Is this the right one or is there a Role that would work better for this?

Or what other Roles could be used?

2
Is there any way to scale the mask?
I often would like to scale down a mask on the lines?

The only way i found was an invisible frame.

3
Could you move the mask on the lines?
It seems that the Mask is always placed in the center.

4
As i remember right we could use more then one Role
on a Object.

Could this be a way to scale and move a Mask
on the Line Grid ?

yes, the "Adjust Profile with Mask" is the feature for this. Transparency Content role for the mask is fine.
Only adding an invisible frame to the adjusted object, for now. If there is a good ideas / UI for controlling the mask frame, let me know.
Not possible to adjust center, unless using the invisible frame trick. Maybe some options are needed?
Yes, multiple roles can be added to the same object, but no there is role that might help position the mask.

Thank you

I think the use of an invisible frame is a passable workaround so far.
Even though I would have liked to have this option in the panel from
time to time, with a live preview.

Well, my UI creating skills are equal to zero.
But I'll think about it.
