Dear PaulSev, thank you for your question. We will consider making header pane visible by default, as option for future releases.
In a meantime, I have code workaround, that you can implement, to force Header pane to appear each time form loads.
1) Add Form Load handler for the main form (New editing experience)
2) Run this code inside
window.top.dispatchEvent(
new CustomEvent(
"onControlChannelEvent-LeeCommandBar-Secondary",
{
detail: {
eventName: "command.showHeaderPane"
}
}
)
);
Note: you might need to add some delay, to make sure Email editor is loaded before raising this Custom Action.
