Also, Reading List's Calibre Action has a different name entirely from the menu (View Fanfiction list (x)), which is why it worked when Mark Books failed:
Code:
"active": true,
"chain_settings": {
"chain_links": [
{
"action_name": "Calibre Actions",
"action_settings": [
{
"display": "View list: Fanfiction",
"path": [
"Reading List",
"View list: Fanfiction"
]
}
]
}
]
},
"image": "",
"menuText": "Reading List Test",
"subMenu": ""
