This single line mode is aimed at restoring the intended behavior with Small or None icons. Line breaks will be replaced with commas (Region row) or spaces (Name row). One can toggle this option in UI configuration.
This adds a Game List configuration group box which is similar to yuzu's, with features including icon size setting, row 1/2 text, and ability to hide invalid titles (those without a valid SMDH). I also added a UI tab and moved the language and theme settings there.
