I noticed there was a new version 1.4.3, and tried it out. However I had two problems with it and had to revert to the previous version.
In 1.4.3 it appears that the visor is swallowing one of the hot key positions (command-1, command-2, etc). I usually use hot keys to get to my terminals but somehow the visor claims one of the positions and no matter which order I start the terminal windows, command-1 will suddenly disappear after a few seconds.
The other problem I had is when I use alt-tab, it insists to show the visor when coming from any other app.
Indeed: Opening the visor each time I CMD-TAB to the Terminal is extremely annoying.
This pretty much breaks the normal use of Terminal. Totalterminal should not be interfering with that.
(Re the CMD-N problem: Visor always was taking one of these, but it was kind of random which one. Now at least it appears to consistent it is always CMD-1.)
