How to get the length of a line?

I’m a new user to Linearity, am a long time user of Intaglio, which isn’t cmpatible with M1 macs anymore. I’m used to have measure lines and have to know the length of lines (tilted).
Can you add that function to show the diagonal length to the measurements?
If you do that I’ll happily pay for your product!
Best wishes,
