Possible disadvantages of Okular

    While Okular provides basic annotation features, it lacks advanced PDF editing capabilities like modifying text and images within a PDF.
  • Learning Curve
    New users might find the extensive range of features and settings overwhelming, leading to a steeper learning curve compared to simpler document viewers.
  • Performance Issues
    Some users have reported performance issues when handling very large files, which can result in slower operation and responsiveness.
  • Dependency on KDE Libraries
    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.
  • Mobile Support
    Okular does not have a dedicated app for mobile platforms like Android and iOS, limiting its usability on tablets and smartphones.

Possible disadvantages of Drupal

  • Steep Learning Curve
    Drupal's flexibility and power come at the cost of complexity, which can be daunting for new users and developers.
  • Performance Optimization
    While Drupal can handle high traffic, it requires careful performance tuning and caching strategies to perform optimally, which can add to development and maintenance overhead.
  • Development Time
    Building a site with Drupal can take more time compared to other content management systems due to its complexity, especially if custom features are required.
  • Resource Intensive
    Running a fully-featured Drupal site can be resource-intensive, often requiring more server resources compared to simpler CMS solutions.

10 Best PDF Expert Alternatives for Various Tasks in 2022

Okular mentions (44)

  • Signing PDFs
    If you mean signing as in "signing with your handwritten signature", you could use Okular () which easily allows you to do that. Filling out forms also works nicely. Source: over 2 years ago
  • Alexandria: A minimalistic cross-platform eBook reader
    I was in a similar position lately until I found Okular. Have you tried it? https://okular.kde.org/. - Source: Hacker News / almost 3 years ago
  • Help with PDF's
    I would try Okular first, though, which is free and open source: https://okular.kde.org/. Source: about 3 years ago
  • EPUB 3.3 becomes a W3C recommendation
    KDE's okular might be a good choice. I haven't personally used it for epub but I know it supports it. https://okular.kde.org/. - Source: Hacker News / about 3 years ago

Drupal mentions (28)

  • Is there and easy way of porting a site from d7 to d9?
    I would be interested in some good migration tools, paid ones are also ok. I found a post about this on drupal.org, but it didn't seem like an easy process. It is a multilanguage site with many content types, and a totally custom theme. Source: over 3 years ago
  • Is there any nice group, where I can ask questions, when I get stuck and recieve some guidance instead of crytics?
    You got already good advice, but wanted to point the guide of drupal.org where you can see some tools listed with instructions and channels https://www.drupal.org/community/contributor-guide/reference-information/talk/tools. Source: over 3 years ago
  • MAMP issue after Pro trial ended
    There is a service call GitPod that provides a temporary container Drupal environment. If you are familiar with what is going on around the future of how Drupal modules will eventually be offered up, you will likely have seen the "Project Browser" module as a contrib demo of the approach. It is used for people to give feedback to the developers. So they set up the typical 'SimplyTestMe' but also a GitPod... Source: almost 4 years ago
  • Best Modules for Product and Recipe?
    For reviews, it depends entirely on what you mean by "review". I believe core has a simple comment module, although it may have been deprecated for D9? There are likely many review-style modules on drupal.org that might work, or if you just want to link out to third-party reviews then it could just be a repeating-value link field on the Product content type. Source: almost 4 years ago
  • Leadership?
    They should also use standards tools like Github. The drupal.org platform was certainly impressive 10 years ago, today it's a pain to use it. They ducktape it with gitlab, but really it sucks to have to read documentation to simply do a pull request. Source: almost 4 years ago
