I found the application APIs, but there is no reference about instructing Glue Desktop to use a custom launcher.
Yes, the toolbar can be replaced with a custom one.
You need to:
Below are the entries for those.
Add the following to the root level of your application's config (to be placed under %localAppData%\Tick42\GlueDesktop\config\apps\
):
{
...
"shell": true,
"autoStart": true,
...
}
And add the following to the %localAppData%\Tick42\GlueDesktop\config\system.json
file:
{
...
"useEmbeddedShell": false
...
}
