Possible disadvantages of OpenCV

  • Steep Learning Curve
    Due to the vast array of functionalities and the complexity of some of its advanced features, beginners may find it challenging to learn and use effectively.
  • Documentation Gaps
    While the documentation is extensive, it can sometimes be incomplete or outdated, requiring users to rely on community forums or external sources for solutions.
  • Resource Intensive
    Some functions and algorithms in OpenCV can be quite resource-intensive, requiring significant processing power and memory, which can be a limitation for low-end devices.
  • Limited High-Level Abstractions
    OpenCV provides a wealth of low-level functions, but it may lack higher-level abstractions and frameworks, necessitating more hands-on coding and algorithm development.
  • Dependency Management

  • Make macOS consistently bad (unironically)
    Rectangle [1] is pretty much essential for me because of this. I use only a few keypresses (maximize window, move to one of the halves of the screen horizontally) but that is enough. My mouse very rately interacts with the borders of any window, or those buttons. I had to click on the green one that you mentioned in order to see what it did (yuck).

  • Make macOS consistently bad (unironically)
    I use Rectangle [1] for window management. I only use three shortcuts: full screen, left half of the screen, and right half of the screen. My editors and chrome are always running in one of these modes. But for other apps like Messages, Notes, Music, etc - yeah I don't usually expand them to full screen.
