@tw15egan @joshblack after I created this PR, I was asked to change the name of one of the SVGs. The previously submitted focus.svg needs to be feedback--02.svg-- this would require me to remove focus.svg because that SVG has layers in it that also say focus. What's the easiest way to make this swap at this stage of the pull request?

[joshblack]

Hey @dudley-ibm! 👋 Feel free to rename focus.svg to whatever the preferred name would be! Since you are adding this in this PR, and it's not in the library yet, there's also no need to worry about the deprecation flow and you can just make the changes directly.

@dudley-ibm I've goen ahead and updated focus to feedback--02. This included:

• Updating pictograms.yml
• Updating categories.yml
• Changing the svg name in the src directory, as well as editing the id of the actual svg element

Let me know if this is what you had intended to change 👍

[dudley-ibm]

Thanks @tw15egan! Here's what I was trying to accomplish:

1. Downloadable file from IDL should be the asset I provide. For a while @joshblack made that happen but in this last release of pictograms, that is not the case (attachment, see pasteboard size difference/layer naming).
2. In submitted SVG, the artwork lives on a layer that has a matching name to the file itself. Wasn't sure how to accomplish that through the UI without flat out replacing the file.
3. All this may be moot with the upcoming replacement files that will be outlined (not stroked) and a 32x32px paste
   board instead of 48x48px.
