Show .ico and .icns files in FileSystem

[AdriaandeJongh]

Describe the project you are working on

A tower defense game called Rift Riff and soon a sequel to my indie hit game Hidden Folks.

Describe the problem or limitation you are having in your project

The Project Settings contains fields for macOS and Windows native icons with the .ico and .icns formats respectively. However, those type of files don't show up in the FileSystem. When my artist wanted to updated the icon, he naturally thought he only had to replace the .png to update the icon everywhere. This is a discrepancy.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Show .ico and .icns files in FileSystem.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

if file_ext == "ico" or file_ext == "icns": show()

(j/k. I don't know how this stuff works internally.)

If this enhancement will not be used often, can it be worked around with a few lines of script?

The discrepancy can just remain there I guess. You can obviously select the files in the Project Settings anyway, but that's not the point here.

Is there a reason why this should be core and not an add-on in the asset library?

What FileSystem shows and doesn't show seems to be part of core, no?
