A sample, local Multimedia Menu with several previously made streaming media (Internet Radio and Television) launchers
MenuLibre is an advanced Menu Editor that allows you to easily and graphically create, arrange, hide, show and delete launchers. We’re going to search for it in Software.
MenuLibre is available here as both a Flatpak and a Deb
Once installed, MenuLibre will be known as Menu Editor
The Menu Editor’s first look at the Main (Applications) Menu
We’re going to use MenuLibre to create a new Directory (category/folder/menu/sub-menu) called Entertainment. Click the green plus sign and select Add Directory from the drop-down menu
Select the New Directory field and type Entertainment. Select and type in the next field to Add comment (optional)
Click the folder box to add an icon and select Browse Files…
Navigate to an appropriate image. We’ve got all our entertainment images in /username/.local/share/icons. We select Entertainment.png and click the [Apply] button
Click the Save icon – a downward facing arrow
Move the Entertainment directory/menu down by clicking the downward-facing arrow at the bottom
Click one of the previously made streaming media launchers and the up arrow to move it up under Entertainment
The Entertainment Menu shows a downward-facing triangle once a launcher is under it and the launcher is indented
Repeat the process for every launcher appropriate to be under the newly created Entertainment category menu
The Entertainment menu
Using the same process, we’ll add two new menus; Radio and Television
And split the Entertainment launchers between them
The Television Menu selected
