Doesn't support multiple CSS files

[SugarD-x]

The Theme Manager does not support custom or extra CSS files. It only looks for the default.css file. If a user needs to override other CSS files or add their own, they have to modify the plugin to load them, or edit the core CSS files included with MantisBT.

The only other alternative is to add their changes to the theme's default.css file and override it with "!important" if it already exists in the default theme, which can cause problems.

To fix this, the Theme Manager should be set to automatically detect all files with the .css extension in the theme's folder, and load them.
