At ~175 MB with a blank drawing open, I've seen worse. Some things I noticed about the menus (on Windows): - The menus don't have hotkey support (Alt+…) - The File menu is missing a Close option - Submenus swich too soon on diagonal mouse movement I'd suggest switching to native Windows menus. From other Electorn apps it seems this should be possible. I'm sure a way can be found to make the menu search feature work, too. Another small note: on Windows, the close confirmation has the newer multi-option layout, the same you'd get when overwriting files in Explorer, but it only has an option to save changes. There is a cancel button, but that should really be an option. Edit: memory measured with: Get-Process -Name "draw.io" | %{$_.PM} | Measure-Object -Sum I don't know if that's the right way to go about it.
