I am looking for the equivalent of git log --pretty=fuller
in Tortoise git. https://tortoisegit.org/docs/tortoisegit/tgit-dug-showlog.html for example consistently just says "date" while there are two dates -- and Tortoise Git actually allows you to alter one of them.
You can open the context menu on the columns (as in Windows Explorer) and select the columns you want to see (or change the order or the sizes).
