Couple questions:

1. What would your usecase for this be exactly?
2. Why not use css to round the corners of undecorated windows?

My guess is you're trying to hide the ugly default titlebar on macOS, but if that's the case you need to think about this problem differently. On macOS you shouldn't use decoration: false but rather make the titlebar transparent. Support for this (if you're not comfortable with implementing it yourself) is coming with this pr: #3965

[Luciennnnnnn]

yeah. I want to customize titlebar to get a consistent visual experiment between Windows and macOS.

I have forgotten the details of why I need a plug-in, I have a discussion on #app-devs channel of discord with @FabianLars (and this channel now is closed, I can't search our past discussion) . The conclusion is that we need native round-corner support other than implementing it by CSS.
The reason may be that we need to set [tauri.macOSPrivateApi] to true to enable transparent window on macOS, and this prevent app be accepted by apple as I remembered. see #3481

@JonasKruckenberg This is the convo: https://discord.com/channels/616186924390023171/622768087183130673/974651874441572363
Btw we need to make the archive public again (read-only ofc), there is much lost info rn.

And yes, you're essentially looking for #3965 like Jonas said (note that the transparency he mentions is not the private api stuff)

Do you mean that we no longer need a rounded plug-in with #3965 ?

[FabianLars]

Yes, same for the shadows plugin (on macOS)

That's great. I'm looking forward to using this feature.
