Hi Frits,
Is it possible for you to rename the track right click “Effect” drop down list to “Replace Effect”? “Insert FX Track” is quite clear but one can easily replace an Effect track using the right click “Effect” menu. But its not made that clear.
I noticed that busses can also be inserted from the “Effect” menu. Maybe they should have their own “Bus” command in the same right click menu to avoid confusion? That will then show options for “Insert Bus” and “Replace Bus”. :-k
