IS THERE A WAY DRAFTS AND OUTBOX CAN BE HIGHLIGHTED?

For Zoho mail in CRM, I have a question, resulting from a delayed email. I put an email I composed into drafts, as I was waiting for a piece of information to complete the message. Things being as they are, I forgot that the email was in Drafts. I was sure I had sent it. It sat there for several days.

If the 'Draft' button on the left had been highlighted and stayed that way immediately an item was saved there - as gmail does, for instance - that would have helped trigger my memory. I know when there is mail in the inbox, and spam, etc., but if I put something in Drafts, there nothing to indicate this. Needs to be changed.
