This is just feedback on functionality and design. I am using the comment function, and there seems to be an error when using the letter “R”. When you type R, it rotates the comment, it doesnt enter R into the box - I assume that it setup for keyboard commands, but it is not clear how to bypass or turn off. .
Also, the use of comment isnt very intuitive. It appears you have have to type in the word in the side box, not the comment label itself, and then click on the side of it to actually enter the text- that box does not stand out, and is not clear that it actually serves as an enter button.
