* There is a bug with pyqt5<=5.14 where the table does not update after a call to update() and needs to receive a mouse click event in order to repaint as expected.
* This does not affect Windows only as this is a Qt5 bug.
* This seems to be fixed with pyqt5>=5.15.1.
* For some reason the table view doesn't update properly after the test string button is clicked nor when the input field is edited
* The table rows only get repainted the rows properly after receiving a mouse click event
* This doesn't happen on Linux
* Add testing feature to Exclusion dialog to allow users to test regexes against an arbitrary string.
* Fixed test suites.
* Improve comments and help dialog box.
* Concatenating regexes into one Pattern might yield better performance under (un)certain conditions.
* Filenames are tested against regexes with no os.sep in them. This may or may not be what we want to do.
And alternative would be to test against the whole (absolute) path of each file, which would filter more agressively.
