Could this small improvements be possible.
1. Refresh Database. I open a text editor along with this app, and when I made changes and save file via the text editor, the refresh button is not working.
2. I am aware that there is keyboard shortcut Ctrl+A for Select All but it will better if there was "Select All" and "Deselect All".
3. Save Selection and Load Selection. When Users select "Load Selection" the program auto selects the games that the user have select.
4. Set Default Database. The program could write a .ini or a settings file. When user select "Open Default Database", the program load the file written in the settings file. Could also save the selection settings (Simply uses game ID) for 3.
