Can we add Focus()/Blur() function in list? Or Do we have these function for list?

[chengxilo]

I am working on a tui project and I use list as a sidebar of my project. In my use case I need to change the focus between my sidebar and my main conent.
Like this:

But I realize that list doesn't have Focus()/Blur() function so I have to munually prevent list from handling tea.KeyMsg().
Like this...

So, since table do support Focus()/Blur() function, can we add this function to list? If we can, I'd like to do this job.
