measuring tool is a pain because you dont know what you will select until you click it  .  either edge , face, endpoint , etc  .

you just have that clumsy big icon with no precision

you end up doing trial and error until you have what you want.  (plus unselect items is a pain also)

is there no way to preview what you will select ?

I mean similar to selection tool or dimension tools with small icon next to the pointer showing object type

thanks for any help
