Is your feature request related to a problem? Please describe.

I wish to have dynamic title for my quick fix windows, e.g., I open diagnostics in qf then my title should be Diagnostics, I open buffers in qf, then my title should be buffers, etc.

Describe the solution you'd like

title field could be a function that returns a string, this way every time a new window is opened, title string could be obtained from this function.

Describe alternatives you've considered

You can use regular winbar syntax to call a function in the title, such as %{%v:lua.custom_title()%}. Once #46 is merged, the width will be calculated properly for format strings. Hope that helps
