Yes this would be awesome!!

Yes I agree with Ronald, by swapping it should only show replacements for the specific exercise you are wanting to swap.  This will save time between exercises

Downloading the data for me, however both would be great to have because it's only a matter of time that I will want to create my workouts / programs as Mac has suggested.

I don't understand the the issue.  What does UI mean?  

This will be excellent to be able to add notes to each exercise. For instance yesterday I was doing 30# laterals and due to an old injury my right shoulder was hurting and couldn't do as many reps.. It will be great to add that as a note for reference.

What about adding a timer to the workout.  Once the first exercise is started the clock starts and ends when the complete workout is finished.  I always try to decrease my total time of the complete workout session to increase my cardio as I workout. But sometimes I get started and don't take notice of the time when I started.  Thanks,

I agree with all of the above comments and working in 2.5 increments is not feasible so I always round up.  But when I do Tri push downs the program was having me do 220 lbs which the stack only goes to 200.  I add 2- 5lb weight to the pin at 220 lbs and increase the reps and I loose ground with the program that I didn't meet the goal.

I agree it would be nice to be able to switch to a different exercise on the fly.  For instance if the program exercise is set up for shoulder presses, I have been doing those on a smith machine.  If the smith machine is being used if I could change to shoulder presses on a machine that would be great. Also, the program has me doing 227.5 pounds on my tri push downs.  The stack machine only goes to 220 and I add two 5lb weights to get to 210.  The program should be able to allow me to lower the max set weights and adjust the reps accordingly.  I add the reps to the finished set however the program should be able to make this adjustment so I'm not guessing.
