You see my English knowledge is limiting, so I can’t investigate the various documents installed by the programmers. There exists one real condition: The TotalFinder’s tabs disappeared from the windows and, regardless of efforts, they never come back again.
No, I do not uninstall and reinstall TotalFinder because it works as part of MacOS Sierra and if I haven’t to reinstall Finder, I will not reinstall TotalFinder also.
It was very nice product for as long as it worked for me, so nice, which makes me to thing if is better to return to MacOS El Capitan.
I hope someday Apple’s Finder to work as TotalFinder. Have a nice day and a brilliant future!
