Feature: comments, notes, journal

[alirezaalavi87]

Hello,
Thanks for the great app.
A huge feature that the app is missing for me is being able to add notes under each exercise. for example: "didn't feel well on the squats, should not lift heavier until form is perfect." or "following the XYZ training method" (just some examples).

Having a little journal and keeping track of your inner dialog is very important and helpful in lifting.

Thank you.
