A simple mpv playlist manager written in Qt.
You probably want to create a directory somewhere and check this out there. i.e. open a console and type the following commands:
mkdir -p ~/src/mplaylist
cd ~/src/mplaylist
git clone https://github.com/cmdrkotori/mplaylist.git
cd mplaylist
qtcreator mplaylist.pro
To compile, click 'configure project' using the default settings and press the arrow button in the bottom left corner of the window.
After this the binary should be at ~/src/mplaylist/build.../mplaylist. Pin that to your taskbar, create a menu entry, place it on your desktop, or run from the commandline.
The application calls mpv to play files, so Windows users please make sure the binaries are in the same directory or mpv is in your path. You may want to install mpv with chocolatey for this purpose.
