selecting
Selecting mails to delete has been a pain. The delete all unread button is not visible on interface until you select a mail. PLEASE increase visibility for this.
Even the touch radius of selecting multiple mails allows too much room for user error. I'm trying to select the checkbox for multiple emails but when I'm trying to do it fast, I misclick outside of the checkbox and it opens the mail instead. please increase the radius of that area so that i can select multiple to delete without a misstep.

You can still bulk delete or Delete All. From your Inbox, just click on any checkbox and a new checkbox will appear at the top. From there you can Select All and then Delete All. Hope this helps.
