[ ] Use constants instead of magic strings like in mainwindow.cpp _ui->findDuplicates->text() == "Stop"
[ ] Make functions constants if they do not use state
[ ] Check imports if really necessary and also which ones might be mission
[ ] Investigate not used warnings
[ ] Refactor functions and interactions to make overall program more simple
[ ] Investigate static Db implementation where the Db location is store in static variable and no object created every time for Db access
[ ] in mainwindow.cpp investigate the _everyVideo video pathnames list uses to see if it could be made more efficient, for example while adding videos to list checking for duplicates for(const auto &alreadyAddedFile : _everyVideo) is a for loop each time, not very efficient !
[ ] Find TODO-REFACTOR comments in code for places that might be good to look at
_ui->findDuplicates->text() == "Stop"for(const auto &alreadyAddedFile : _everyVideo)is a for loop each time, not very efficient !
