Suggestion: custom CSS themes
The idea gettting custom CSS themes is possible? i was doing some testing and somewhere on line 3652 i just added
if(file_exists(__DIR__."/custom.css")) echo file_get_contents("custom.css");
Adding a single line could lead to designers to submit custom CSS themes

The same goes for custom.js .
I could do a pull request of both. Would that be okay?
Are there any new developments on this subject?
I would also find a custom css extremely usefull especially for things like setting a max-width for the main layout so that the filemanager does not spread across the whole browser-window (More user-friendly in some cases).
I'd love to propose official support for an optional custom stylesheet that:
- is registered in
$externalonly if it exists, - and can be safely printed via
print_external('custom-css')in the template.
Example Implementation
Add below line 166:
// Uncomment & modify the following line to add support for custom stylesheet
// $customCssPath = 'theme/custom-style.css';
if (file_exists(__DIR__ . '/' . $customCssPath)) {
$external['custom-css'] = '<link href="' . $customCssPath . '" rel="stylesheet">';
}
Add below line 3829 and 3993:
<?php print_external('custom-css'); // add optional custom-css if it exists ?>
This keeps things clean and avoids breaking anything if no custom style is provided.
