COS:

• Implement icon bar on the left
• Continuous page
• Headings for sections that didn't have headings before (i.e. a heading for each tab)
• Selection status for visible section
• Clicking on the icon scrolls to that section
• Remembered state of the Detail View when navigating through issues or modes (current functionality - don't break it!)

Development Notes

Q: Make sure this plays well with all existing functionality, such as keyboard shortcuts and moving tabs.
A: We need to remember the currently selected 'tab' when moving to the next issue or returning to the mode.

Q: How do third party icons affect this layout?
A: The icons will occupy the same space which is a maximum of 16px x 16px

Q: How will resizing of large inline edit fields like the Description field play with the new continuous page and jump navs?
A: It will move the content below relative to the change in size.

Q: Will users be able to switch back if they don't like it?
A: They'll all like it There is no option for legacy versions, only for continuous improvement.

Q: Do the jump navs work ok when zoomed and at all supported window sizes?
A: Window size should not make a difference, though resizing will be taken into account for the size of the detail view content.

Q: Does tabbing through the tabs still work?
A: They won't be tabs, but they'll be accessible using the tab key as before.

Q: What if some fields are hidden from the default screen (like Description)?
A: They should be hidden.
R: Please test this.

Q: Are the icons always hidden when the detail view is closed? Should they be displayed?
A: They will be hidden since they are within the container that is removed.

Q: What happens when the item counts exceed the available space?
A: Unlikely with expected usage but expected behaviour is to overflow into content area. Clipping or ellipsis would not help much. We can fit 5 digit numbers before this occurs.

Q: What happens when the nav items exceed the available space?
A: Unlikely with expected usage but possible as there's a plugin point there. After a point they would be clipped and unavailable to click. Content can be accessed by scrolling.

Q: Does the Detail View render ok when no issue is selected?
A: Yes, note the DV has a single column in this state for Plan mode. In Work mode it closes.
