- restore previous pattern when search bar is invoked by hitting F3.
- clear highlight selection when there's no match.
- disable next/prev buttons when appropriate.
- fix focusing of lineedit not working in some situations.
- fix labels not being erased, add "Not found" label.
- use smaller spacers so that label is readable on a 800px screen.
- fix uninitialized variable.
