That one’s not bad, except that it looks like they waste a lot of screen space on chrome, and I can’t tell if you can collapse the compare to a higher level and still see the compare status.
on Chrome? I wouldn’t know how it runs on Chrome. I’ve used the Windows version for years. Yes, it lets you collapse the hierarchy and the level of difference indicators still show the highest directory that something is or isn’t ‘the same’
It does compares for file and folder, deep compare or ignore unimportant differences, also Sync as in Update one or both sides/Mirror one side to another, etc.
