Some people are still unhappy with "standalone window mode" of "Add new torrent dialog" so just provide them with an option to use old "modal dialog mode" in all the current qBittorrent branches.
PR #22492 (based on original PR #19874).
Restructures the code to separate the basic logic from the logic that depends on the parameters and properties of the torrent being added.
Also fixes "Never show again" checkbox functionality.
PR #20848.
Allows you to bring the main window to the front when one or more "Add new torrent" dialogs are open.
Also allows you to minimize/maximize the "Add new torrent" dialog.
PR #19670.
