This would be extremely helpful as clients send requests like "see edits highlighted in yellow" but then I have to go find the original email to see what was highlighted.

Having links hyperlinked would be helpful too as right now i have to copy/paste all the links clients send me.

Another idea... which Clickup does when you 'email to a list' is they attach a copy of the email to the task as a HTML file so you can at least refer to it easily.

Agree. This would help with task-specific conversations
