I've been using Total Terminal (former Visor) for a while now. With the new High Sierra update to osx when I try to open a new tab with CMD+T it ends up opening it like a new window, separately from the sticky tab I already have opened. I have to mention that it worked great on Sierra.
I've checked the settings and I have "open with same profile" and "open in same working directory" checked. Also I've entered Recovery Mode and set the
csrutil enable --without debug which Total Terminal needs starting from El Capitan.
The Total Terminal web page says it's not currently under development and High Sierra is not listed under Compatibility.
If anyone managed to find a fix around this, it'll be highly appreciated. If not, I'm thinking about switching to iTerm2. Apparently the developer of Total Terminal recommends doing so too.
