nostalgia-vscode (for macOS)
The icons of VSCode 1.17 look ugly (issue #35783 on VSCode's github repo).
The following files are from VSCode 1.16:
/Applications/Visual Studio Code.app/Contents/Resources/Code.icns
/Applications/Visual Studio Code.app/Contents/Resources/code_file.icns
/Applications/Visual Studio Code.app/Contents/Resources/app/resources/letterpress-dark.svg
/Applications/Visual Studio Code.app/Contents/Resources/app/resources/letterpress-hc.svg
/Applications/Visual Studio Code.app/Contents/Resources/app/resources/letterpress.svg
Acknowledgement:
Code2.icns
was created by @1|0 (here). Thanks!
Update: a nice script to change any file or directory's icon programmatically: fileicon.
