+Improve accessibility:
+- Disable tab-key navigation in tables, so focusing a table does not lock global tab-key navigation to it.
+- Remove some container widgets, tweak focus rules to avoid extra unnecessary steps when using tab-key navigation (like selecting the dictionaries widget outer frame).
+- In form layouts, link each widget to its label (like each option in the configuration dialog).
+- Set the accessible name / description of focusable widgets.
+- Use lists for the dictionaries widget, suggestions widget, and the paper tape.
