Just reporting a minor bug. With the most recent version, when I finish a SDL project and export it to txt (from grammar check in another program), CT puts the sdl extension instead of the txt extension. It didn't do that with the previous version.
So I have to remove the sdl extension (don't remember exactly, but I think its SDLPPX) manually and to change it for txt before saving the file.
It actually appends the .txt extension automatically even if you don't change the suggested one. I agree it would be more intuitive to suggest the .txt directly in the save dialog.
