In Thunderbird 3, bug 480623 moves compact header view to an extension. Please list specific use cases where compact header is helpful and/or normal message header gets in the way. A use case in this context must include a specific type of mail, often a specific type of user, and circumstances of how work flow is impacted. The purpose is to collect information which will later be organized, discussed, and used toward the end goal of a) improving how compact header view is supported, and b) helping specific use cases where improving compact header is not sufficient to significantly improve the use case.

The "need" for vertical space and your passion for the need are of course assumed, and so should be omitted from the use case (see #Notes_and_Assumptions). Discussion and promoting one's position beyond the specifics is a non-goal. Generic use cases are not helpful. A short one or two sentence description limited to how the message pane is used in a specific case will be most helpful.

Use Cases

Viewing photos from family & friends, which are typically taller than the preview pane. Users should be able to see at least one *full* photo without scrolling.

Reading newsletters, which are always longer than the preview pane is tall.

Reading newsgroup threads, which are typically taller than the preview pane.

bugmail - for a triager processing incoming bugmail most of the standard header information is not useful (To/From, etc), often much of the top of a bugmail is not very useful, and extensions like bugmail extension need a couple lines to display bug details from mail header and other sources (eg bugzilla). Reducing header space would result in less initial scrolling of each bugmail, which is often done in large batches.

E-cards that show web-like content (where content is more important than UI)

Newsgroups graphics (stationery) posts that assume a larger viewing window. As compared to OE, we offer an 8% reduction in size.

Chain-letter e-mails with long texts that extend beyond the view-port.

e-mails with (many) attachments where the additional attachments pane (on the bottom) further reduces the size of the view-port.

e-mail conversations where the participants use interspersed quoting (like in newsgroups).

e-mails with long texts (e.g., a "letter" from Mom).

e-mails with very large fonts (e.g., from elderly AOL users).

e-mails where the sender used bottom-quoting (Thunderbird's default setting - unfortunately).

Business e-mails, which often have vertically long signatures (to see the contact info).

Reading e-mails on smaller screens (e.g., the very popular netbooks) is very painful with the huge header.

Notes and Assumptions

Compact header view would be less needed if the normal header were kept to a minimum or if it scrolled with the message.
