Any way to disable the window frame?

[OsakiTsukiko]

Is there any way to disable the window frame (something similar to what electron has), mainly for custom window frames?

It has already been implemented, but currently it's only available in nightly version.

Please refer to #417 for more information.

Yes, but still underdevelopment.
As @OsakiTsukiko said #417.

Frameless support is added: https://github.com/webui-dev/webui/tree/main/examples/C/frameless
Windows looks fine, Linux and macOS still need some work to drag and move window.
