Hi @sdaitzman :) What does the "+ Add content" button do in this context, when all the new/existing content buttons are in the main page area?

[sdaitzman]

Hi @pomegranited!! The new/existing content buttons in the main page area in this ticket are a shortcut that will only appear in empty units, to help users get started authoring the unit. The "+ Add content" button still always opens the Add Content sidebar. Basically, instead of an empty state, we're including a direct shortcut to add a first block.

Once there is ≥1 component inside the unit, that inline shortcut goes away, and users use the Add Content button in the top right, or Add new / Add existing shortcuts underneath the components. Both open the Add Sidebar to the corresponding state.

These workflows are a bit redundant, in the interest of making it very straightforward for users to add content to a unit. If we want to cut more scope from #1594, we could drop some of these options, or reuse the same Add New / Add Existing main view for empty units. Let me know if it would be helpful to mock that up?

For Teak, based on Libraries product discussion with @jmakowski1123 today, if it helps to reduce scope: can largely just drop-in existing new content object from course authoring, and allow the new incremental Add sidebar "Existing Components" button to handle library component reuse in new units.

@sdaitzman @bradenmacdonald @jmakowski1123 It looks like this task was excluded from Libraries 12 for Teak? It was moved down to "Dropped for now" on our estimates sheet.

Instead of this task, we have #1620 + #1619

Is this correct?

[bradenmacdonald]

@pomegranited Yes, I thought that we were dropping this story entirely; since it only affects the empty state and you can add from the sidebar.

Though perhaps it would also be very easy to put in the existing "course" version of the "add content" workflow as an alternative, which is how I interpret what @sdaitzman just said.

@pomegranited @bradenmacdonald I wasn't sure if this story was dropped or scaled down from the estimates; the suggestion I added was for a scaled-down version. Completely fine to defer this until after Teak, will move it to post-Teak for clarity.
