This update adds the config option "icon-size" to make it possible to adjust the size of the icons. Also, the set-marker command has been revised. It no longer needs "|" as a separator, but the option "description" has been removed.
To get line breaks, now you have to use HTML/markdown tags. Also, the command is now much more flexible - none of the arguments are mandatory. You decide what you need or what you want to declare.
