After a few short hours with Max 5, here are some of my favorite things (the list is already too long, had to trim it down):
* bpatcher scripting coordinates are relative to the bpatcher. Fantastic. Thank you so much for fixing this!
* The new "Tab" object. Should be very useful for interface building.
* Alpha channel support.
* "Show Object" feature in the Max Window, works via double click too. Very handy.
* Shortcuts for creating objects ('b'=bang, 'f'=float, 'n'=new object, etc). One of my favorite features from Max toolbox.
* Alignment/grid features.
And of course the new help/doc system is just great. What a huge improvement. It really shows that Cycling '74 cares about usability and making Max a joy to use.
Also really looking forward to using the new time system. I think this is going to solve some synchronization difficulties that have been surfacing in my overly-complex sequencing patch.
