Feature: #70002 - Make it possible to register own icons for file extensions ¶
See Issue #70002
The IconRegistry has been extended with a mapping of file extensions.
It is now possible to register or overwrite the iconIdentifier for a file extension.
$iconRegistry = GeneralUtility::makeInstance(IconRegistry::class); $iconRegistry->registerFileExtension('log', 'icon-identiifer-for-log-files');
