The issue with the Inbox buttons (New, Reply, Reply All, Forward) is that they seem to be getting smaller on each release of the product. Whereas they used to be prominent and stand out at the top of the Inbox view, Now in Notes client 12.0.1 it is difficult to see them.
The end user have to hunt for New, Reply, Reply All, Forward buttons, they should stand out.
2. The experience with Notes mail is becoming increasingly difficult to justify to my clients. HCL should take a good look at the Outlook client, who's buttons for creating / replying to emails are several times larger than that of the Notes client.
While comparing the Notes & outlook, it seems the Notes mail layout is going backwards. Buttons at the top of the mailbox view used to standout, whereas now they do not.
