json approach works, thanks!

let myInfoJson;
try {
  myInfoJson = JSON.parse(loadFile('file:///refreshSkinShortcut/info.json'));
}
catch (err) { }

Unfortunately (as far as I can see) there's no simple way to retrieve the addon info from outside the config window (you'd have to do app.getAddonList() and do something like list.filterByPrefix() to get the right addon). But if you like, you could try loading the info.json file with the loadFile command.

Example with the Refresh Skin shortcut:

[code]
let myInfoJson;
try {
myInfoJson = JSON.parse(loadFile('file:///refreshSkinShortcut/info.json'));
}
catch (err) { }
[/code]

var dlg = uitools.openDialog('display', {

function init(params) {
    var try1 = this.version;
    var try2 = params.addon.version;
    var try3 = this.addon.version;
}

I'm writing a display Addon. Following the Getting Started page, I see 'version' specified in info.json. I would like my display addon to show the version, I'm trying not to define the version in multiple places.
My actions_add.js has
[code]var dlg = uitools.openDialog('display', {[/code]
Is there a way for my display.js to access the 'version'? I've tried
[code]function init(params) {
var try1 = this.version;
var try2 = params.addon.version;
var try3 = this.addon.version;
}[/code]
but not found. I saw the config.js addon parameter should have access but I think that would require opening the addon config first.
