Hi @bpasero, you can implement the menu in JS in a Browserwindow and then rendering the workbench in a Webview.

@WaiSiuKei why so complicated, the window can be frameless and own everything, including menu and title?

[WaiSiuKei]

Yes, the browserWindow can be frameless, with menu and title created by HTML. The reason is that when you click the menu, the activeElement of the webview will no change, only the webview itself will be blur, you can focus the webview back and send the actionId to webview just like the menu works now. The fous/blur issue is most concerned. An Opposite Example is ghedit , it inserts the menu before the workbench, but you will find that there is no copy/paste in the menu, it cannot impletement the functionality because the focus of editor is lost.

Ah good point, needs more thinking indeed.
