SUMMARY
Before, i used to organize my applications and shortcuts in different sub-directories, so it would look cleaner in each category, for example:
Launcher > Games > Emulator > Dolphin

But since the anniversary update, i've lost this feature and now my app lists are just a mess, the subdirectories are still configured, but Kickoff applauncher doesn't list them, it puts all applications together in each category and ignores it's on subdirectories.

I searched around the configurations to bring back directories on Kickoff applauncher, but couldn't find it.
I thought it was another misconfiguration, so i asked on the forums, but i was told it is a regression and i was asked to file a bug instead

STEPS TO REPRODUCE
1. If there isn't, open Menu KDE Editor and create subdirectories in another category with items into it
2. Create a default "Kickoff" plasma applauncher
3. Open it

OBSERVED RESULT
After the update, it now looks like:

   * Education
       * Digital Circuit Simulator
       * Micro Computer Emulator
       * LibreOffice Math
       * Geogebra
   * Games
       * KEmulator
       * Dolphin
       * Epic Games
       * Steam
       * Game 1
       * Game 2
       * Etc

EXPECTED RESULT
It used to be, for example:

   * Education
       * Computation
           * Digital Circuit Simulator
           * Micro Computer Emulator
       * Math
           * LibreOffice Math
           * Geogebra
   * Games
       * Emulators
           * KEmulator
           * Dolphin
       * Launchers
           * Epic Games
           * Steam
       * Game 1
       * Game 2
       * Etc
