There are a couple notes I wanted to leave after trying TF again this morning after a few years not using it. The first: everyone already knows, is it requires disabling SIP to use, and run.
The second, which was the main one that frustrated me personally, and why I uninstalled it again, was, it resized all my Finder windows, after install, and opening a window. I uninstalled it, and opened a window that was my original size and navigated in that window to the one that had been resized to restore it. I haven't used TotalFinder since before El Capitan as I just haven't needed the features, even though I paid for a license for it. When I used it, I loved what it had to offer. If there is a way to stop it from resizing windows, I'll try it again.
P.S. I forgot to mention in the original post that I tried TF version 1.11.8 (latest)
I tried it on Mojave 10.14.3 (latest release.)
