git reflog would benefit from including the branch names on entries
Take the current output of git reflog:

Notice that some of the reflog entries show branches that they are on. This would be beneficial to pass through in ugit, both as a property on the reflog entries, as well as formatted to show similar to native git.

Note: The coloring shown here is some done by WindTerm, and some by git itself. I think the colors are helpful, but not needed as part of an initial implementation.
@corbob this one will be a good bit trickier than the others (surprisingly)
git reflog maps down to
git log -g --abbrev-commit --pretty=oneline
Which comes back with branch information when pretty-printed, but not when assigned to a string.
This will take some more digging.

That's caused by the implicit --decorate=auto argument. Log.Decorate
Working args
$color = @('--color=always', '--decorate=full')
[string[]]$render = git.exe log -g @color --abbrev-commit --pretty=oneline | select -first 10
$render
note: I'm using git.exe so that I don't have to unload ugit.
$color = @('--color=always', '--decorate=full')
git.exe log -g @color --abbrev-commit --pretty=oneline | select -first 10
git.exe reflog @color | select -first 10
reproduction
# full color invoke
git.exe log --color=always --decorate=auto --abbrev-commit --oneline | select -first 10
# now only partial color, the hash, is preserved
git.exe log --color=always --decorate=auto --abbrev-commit --oneline
Select-Object and assigning to string were both triggering the same auto, behavior, so I used both interchangabliy in some cases.
( [string[]]$render = ... ) | select -first 10
