Selection Filter's Checkbox Not Checked After Restart
1) Open Musescore and open Selection Filter Panel
2) Close Musescore
3) Open Musescore again
Of course, the Selection Filter is still open, like every other panel that you might had opened at the last session.
But its checkbox in View -> Selection Panel, is unchecked.
So, you have to check the checkbox (nothing changes) and then uncheck it to close the panel.
