Whenever you open a template, Rotato adds that template to the template library, allowing you to quickly access the template again without having to look for the template file.
If you just downloaded a template or got one from a team mate, here’s how to use it and add it to your library. You can recognnize template files by the icon that is different from a normal Rotato file icon, and it also says “template”. Furthermore, Rotato templates have the .rotatotemplate file name extension (but you may not see this in Finder)
