Great work Mike. These are logical and intuitive.
A couple of small things:
* Importing ReaMenus #003 on my laptop (Win7 32 bit) made my REAPER (3.53 pre6) freeze. Once I force quit REAPER and relaunched it, the new menus came up and all is well.
* My main toolbar was replaced with a new one. I'm not sure if this is intentional but some of the buttons I created with my new Neve / Calrec theme don't seem to match the new functions. Resetting this toolbar to default restored things.
A side benefit to this second point is that I discovered some new buttons I need to skin for my new theme.
Edit - One more thing I just noticed....
* My edit menu still shows the default. Perhaps this has something to do with the hang during installation.
