  • Performance Issues
    Some users have reported performance issues when handling very large files, which can result in slower operation and responsiveness.

    To get the best experience, Okular requires KDE libraries, which might not be ideal for users who prefer not to integrate KDE components into their system.

Possible disadvantages of PostCSS

  • Plugin dependencies
    Relying on multiple plugins can lead to dependency management issues, and possible conflicts between plugins if not carefully handled.

    Setting up PostCSS might require more initial configuration effort compared to some integrated solutions which provide out-of-the-box functionality.
  • Plugin quality variance
    The quality and maintenance of available plugins can vary, with some plugins being outdated or less reliable than others.
  • Lack of opinionation
