[Request]: Add a way to change libray item image

[sigzegv]

Tell us the problem or your need

The library is very usefull to aggregate all the executables we want, but it lack a way to define a custom image for an item instead of a auto generated one.

Describe the solution you'd like

Some contextual menu to use a custom local image or an image from an URL.

Question: is there a workaround to change an image for a shortcut using the actual state of the application ?
