I am ok with both diffs, but there is a caveat:

On a non-trivial repository, such as git.git, the tog UI freezes
for several seconds when I press 'b' and then 't'. I don't mind
this problem in the initial version but it would be good to follow
up with UI improvements soon.

There are plans to improve toposort performance by using Git's commit-graph
file, which would likely make this a non-issue. But getting there will
require a substantial amount of work.

Meanwhile, we'll want to avoid the impression that tog is stuck.
The easiest way would be doing what the diff view does, when it shows
"Diffing..." at the top of the window while a diff is being generated.
Even better, we could add a progress callback to the commit graph such
that tag can display a progress percentage or counter while sorting commits.
