no there is nothing like that in the manual

"layer_sort(void* element, var layer)
Places a layered element - a panel, text, view, or a view or sky entity - on a different layer."

gues you have newer version than 6.40 in this case it mean it's possible
good for you

Hello,
I m not able to download any demo file. Please provide me the proper link.

set_layer(PANEL, layer); - this may help for lite-c users.

I've just been doing the same sort of setup with a linked list of panels as "windows". I'll see how yours relates speed-wise, and friendliness wise, and hopefully get around to posting some results sometime

Don
have a great day
