Hi,

Please do send your patches to the list.
The best way is with git send-email, but attachments
also work. Prefix patch subject with the component
it belongs to (for example [spice-gtk]).

Alternatively, if you prefer, you can create an issue
on gitlab.freedesktop.com, as Jakub suggested, and
add the the patches there.

Maybe your patches will not be maintained, but
by sharing them, others can try a better
seamless-mode and maybe even improve it further.

Thanks,
     Uri.
