The plugin is an update of the Task configuration plugin which I had written a diary post on.
When I first created the JOSM configuration plugin it was with the intention of allowing users to directly load the configuration file by providing the gist link. It then occured to me that it would probably be better to save the configuration files incase the user wishes to revisit the task.
In order to do that I decided to automatically load a set of task configurations to a list which would be displayed once the plugin loads.This allows the user to load the configurations as many times as he/she wants and additionally switch between different configurations. A new configuration can be addedhere.
To create a custom confgiuration the user can use this JSON structure:
"project": {
"type": "task",
"name": " ",
