  Honestly, no, thats not what it suggests. It clearly tells if a folder should be searched (magnifying glass) or not (minus sign). Currently a checkbox would do, but thats a) not scalable b) non-obvious (does checked equal included or excluded)?
  
  I have already mentioned meta-data vs full-text. Also file-name only is often wanted.

  Lets see:
  
  - Desktop Effects KCM:  It has 3 state checkboxes where this clearly violates HIG. The "Video" button is a toggle button, but to get its meaning you have to hover it for the tooltip. It has a "Get new Desktop Effects" button on the top button, which not only installs new effects, but must also be used to **uninstall** effects.
  - Activities: "Create New..." on the bottom **right** (HIG violation).
  
  So much for your poster childs ...
  
  Yes, it does use custom buttons. The second one can be trivially replaced by a Kirigami.Action (or I could use "flat" style, and it would look and behave exactly like a Kirigami.Action, so no "custom button appearance" nor "behavior"). The "Enable/Disable indexing" button is custom. It can be trivially changed to a Kirigami.Action by moving the text to the tooltip, but IMHO thats much worse from a usability view.
  
  >> The search/excluded icons are just the first implemented state column. There will be more columns. Having the full state in textual form for each entry will look awkward, and having it in textual form only will make it much harder to get the current state for a given path.

Running full-text indexing on ~/Documents/MyCppProjects/ is definitely subject to a users preference, while most users would expect ~/Pictures/, ~/Videos/ and ~/Music/ to be scanned for metadata.

This definitely gets the model in a usable and extensible state, and shows the real state to the user (instead of showing some invented entries, and leaving out the other real half), and also makes it configurable. The important part here is the model. The view/delegate can be extended even by some person who is not familiar with baloo internals.

Let's do it now, or we might forget to do it later, or do the backend bits in a way that make it impossible to do the UI in a user-friendly way. It wounds like what we really need here is a true multi-column table, like the one in the git master version of the System Tray applet.
  
  Thats not what I said. It has a sound model with this change. The model is extensible. The model represents the configuration correctly. Based on this model, everybody can polish the UI.
  
  If you can provide a better model, a better UI, please do it. The new model and UI addresses all the complaints I am aware of.
