I like to scroll through my Inbox and check/select the emails I want to delete in bulk. So I use my mouse as a pointer while scrolling down the list. However, when I drop down to the next like - to decide whether to keep or delete - you bring up a box with control icons in it (Move, Reply, Star, etc) which covers up part of the subject. An "Unsubscribe" button also comes up on some items and covers the first part of the subject. I want to see the entire visible part of the subject when I hover over an item. Sometimes I have to hover longer to get the full subject to come up. When you cover up part or all of the subject while I go down my list, I have to hover on EVERY email and wait until the full subject pops up. This wastes time. That's one reason I liked "Basic" mail a lot better and want it back. I think "Basic" mail also showed me more of the subject of the mail in the list because the column where the list is was wider. That meant even less "hovering" to see the full subject, and I could work through the list quickly and delete the items I did not want to open.
