I will not do everything that you showed in the first video - this is pointless! I purposefully then open the necessary paths in the file panels in order to IMMEDIATELY compare the contents of the selected files using the
Imagine that you are doing a large sync. where it takes many minutes to do the comparison. Then you see a single file and are in doubt whether that is the version of it, that you want to synchronize. It is much easier to do what I showed in the video to compare it to a master copy, than it is to close down the Sync tool, find both files in TC itself and do the comparison - then open the Sync tool again and wait for the comparison to take finish, and then find the file again in the compared list, and maybe remove it from being synchronized.
And just because you don't want a certain feature, I think it is unfair to others, that might have used that feature, maybe for years, to suddenly deprive them from being able to do that anymore.
