With latest plugin, it will highlight if you have a typo in a MBS function call right in the calculation editor.
The name turns red (or whatever color you defined for wrong brackets) and turns back to the default text color if you type the name right.
We think this is a good addition. The plugin has the list of functions anyway and we know you just typed the MBS with a string following it. So we just put the pieces together.
Have fun and see you at the next conference in Salzburg or San Antonio.
