It would be great to be able to change the window title dynamically, not only during creation. I'm working on an editor app, and at least on Windows, the typical behavior is to display the path to currently open file in the title.
Indeed. I think the API should be to add a SetOptions to Window and reuse the existing WindowOptions such as Title. See also https://github.com/gioui/gio/pull/10#issuecomment-757484484.
I don't know whether ~inkeliz is working on SetOptions; I suggest you notify him on the PR if you want to avoid duplicate work.
looks like ~inkeliz beat me to it, I'll be happy to test this is action as soon as I have been able to update my project to the latest version of Gio
