Enhancement: In the horizontal layout, allow columns that always display certain stats rather than overwriting them during a live run

Nobody has claimed this yet.

In horizontal mode today, there's no way to permanently display a segment time. As soon as you split, the time is updated to reflect the current run.

For example:

I want an option for a new column that would display my "best segment" times at all times, even when I've split in that box.
That way I'd be able to have side by side my live total segment time and the overall best time for that segment. Perhaps you'd have the option to pick whatever stat you'd like, but right now the default behavior always seems to overwrite a column rather than having any way to keep data permanently on the screen.

The issue does not name files, tests, or entry points. Start by locating the horizontal layout and column/stat rendering code, then trace how segment times are updated after a split. Done means users can configure a column to keep a selected stat, such as best segment time, visible alongside the live value during a run.
