Just want to thanks Nfx of templates video. I tryed not so long ago to make my own template, but I just saved it into the templates directory. It didn't work because I didn't know that you need to start fl after saving it. It  also seems that if you save your template fruity file into templates and don't create folder and then saving your  template there it just shows plank space when you try to open it from file/ templates. 
I saved my template like in the video and now it's like it should be

Thanks Nfx
