Does it make sense to expose the items variable in the Flex primitive (https://github.com/rivo/tview/blob/master/flex.go#L31) ?

The reason I am asking is I have a simple 4 column layout where I would like to cycle through each column when a certain key is pressed. Right now I've setup a SetInputCapture() to listen for the key press and then SetFocus() on the next item, effectively moving the focus from column to column. The problem with this method is that I need to hard code the primitive that should get focus next. It would be awesome to be able to just use something like flex.Items[n+1] or something similar. Since the data is already there in the items variable, it seems like a great data source for something like this.

Hey @esell, does a Flex.GetItem method which returns the primitive at that index solve your use case? I will submit a PR adding it if so.

Good timing @tslocum :). I actually just swapped out for your cview and used the Flex.GetChildren (https://godoc.org/git.sr.ht/~tslocum/cview#Flex.GetChildren) function, it was exactly what I was looking for.
Before that I was just keeping track of everything in a slice I created.
