 - [x] remove this top-most line above the panels on the right-hand side: `dbdash │ SQLite │ READ ONLY`.
 - [x] highlight the current cell isntead of just the current row in the results pane.
 - [x] put the help text inside it's own pane so it fits the design more cleanly.
+- [ ] move the table name in the results pane from the bottom-left border title to top-right border title instead
+- [ ] remove the bottom navigation help panel and have a keybinding overview appear in a floating window when pressing `?` in normal mode
