For memos in particular, the current "one line per item view" does not work very well, and is a very inefficient use of screen real-estate. One line-per-item works well where there is a lot of relevant information about each item - so it works well for emails (because you want to see who it's from, what the subject line is, and when they sent it), and it works well for contacts (where you usually have name, email, phone, position, company), and it's mostly okay for tasks (if the task description is quite detailed). But for memos, all that really matters is the name of the memo. This means the current table view of memos is quite inefficient, because most of the screen space is wasted. It would be better if multiple columns were added, that way many more memos would be visible at once. For example, I have 257 memos in one folder, and in Evolution I have to scroll the memo list regularly to find what I was looking for; However I know from using Outlook previously that I can fit all of theses memos/notes on screen at once in a multi-column view on my monitor, without any scrolling.

Will attach an example mockup of what I am describing next to help illustrate.
