Better Popup Launcher is a Plasmoid for KDE Plasma 5, built upon Popup Launcher.

It adds an icon to the KDE Panel which loads a menu with application shortcuts, as selected by the user.

Compared to the original Popup Launcher, it comes with the following improvements:

You can add separators to the menu (separators can be thin lines, or spaces);
The position of the apps in the configuration window can be changed by drag and drop, rather than by arrow-clicking the tiny menu previously available (now no longer included);
The Panel tooltip actually works, and you can set a subtitle to it (did not work previously);
You can pick an icon for the panel using the KDE icon picker, rather than browsing the File open dialog;
The versions of most components imported into the Plasmoid have been updated.

How to Install

..or else, look for "Better Popup Launcher" among the new Widgets directly from your Plasma desktop.
