Is there an option to turn on the measurement tool on the cursor? like in this attached photo

This one has already been requested in the feature request section and shows "under review"

Measurement appearing beside cross hairs while doing linear and area takeoffs | zzTakeoff

This will be released soon (likely later today).

Also, a reminder about a related feature: you can use arrows as well to draw exact dimensions. For example, if you're in the middle of taking off an area or linear, you can press the right arrow, and enter 10' to draw a line exactly 10' (same for other arrows, and you can use the diagonals on the number pad).

It's up. Very nice!

Thanks, Herber & Kory!
