Fullscreen does not work in Play in Editor (New Window)
When running Play in Editor in a new window, there is no way to make the game fullscreen.
The only way I can get fullscreen is to use Play in Editor in a window and then maximise the viewport (F11) and fullscreen the editor (shift-F11), but that's awkward because I then have to un-maximise un-fullscreen to get the editor back after exiting PiE. Standalone game also works, but takes much longer to load.
Pressing alt-enter in a PiE window should make that window fullscreen (or preferably borderless-window fullscreen) There should also be an option to always make PiE windows borderless in general.

Since Epic have refused to fix this for two years, and have instead marked the bug "Won't fix", below is a workaround to add fullscreen support to the Play In Editor / new window, using AutoHotkey. It can also open the editor window in fullscreen by default, and automatically clicks into it to capture the mouse.
Note that you will need to have AutoHotkey installed to use this script. Save as UE4StandaloneFullscreen.ahk and run before using the editor. Add it to system startup if necessary.
