Is this just for trimming moldings at doors and windows? I'm thinking of its possible uses in all aspects of woodworking - cutting and measuring mitres etc. I'm a newbie to woodworking and looking for helpful tools. I know there's plenty of gauges and jigs around, but this seems like a good alternative to other tools. Responses would be really appreciated. Thanks in advance.

BEST ANSWER: Like in any shop whatever you use to get a job done works! I always find different uses for tools that were not it's intended use. This is a good tool to have, it is pretty specifically designed but at 12$ it is good to have.
