+  === Change CSS dynamically
+  \
+  - Highlight of top 4 layouts
+  - Custom signals not working
+  - Solution: Using custom actions to change CSS
+  #pdfpc.speaker-note(```md
+    - custom signals  it would need access to the implementation of the widget
+      - else you would send a signal in reponse to a signal
+    - actions are function because that can be assigned to widgets and called via string
+      - advantages: reusable code, can be called from anywhere where widget is available
+    - if i have to bind to an existing signal and call an action, why not inline?
+      - certain information not available in the signal
+        - e.g in add keyboard layout no access to user keyboard layout list
+    ```)

+
+#polylux-slide[
+  === Nested groups
+  \
+  - ListBox always selecting a row
+    - selecting back row, which triggers an action to go back
+  - Some rows have different logic depending on if variant exists
+  #pdfpc.speaker-note(```md
+    - Solution: Grab focus of another widget so no selection is triggered
+    - Rows with no variant need no action
+    - Rows with variant have a on click event to override keyboard layout list
+    ```)
+]
+
+#polylux-slide[
+  === Flatpak Sandboxing
+  \
+  - GIO cannot access the system schemas
+    - GSettings subsequently not working as well
+  - Solution: Use flatpak-spawn to spawn commands outside of sandbox
+  #pdfpc.speaker-note(```md
+    - this problem is will happen to all plugins that need to access system schemas
+    - schema is a db file that contains the settings of the system
+    ```)
