Every tab and sub-tab, refiled onto five rails
Read from the shipped sidebar catalogue and the tab shells. Nothing is deleted — the three-level tree becomes one rail plus one visible list, and the command palette reaches any screen by name. Every screen below is now drawn, in both themes, plus the states each of them needs: empty, loading, selected, failed and phone. The list column can be dragged between 148 and 320px, or folded to the rail and hovered to peek. Rail letters are the g-prefix jump keys.
Where the depth went
Today the sidebar is section → subsection → item, with two tab rows on top of that. Console keeps two levels only: a rail, and one visible list. Anything deeper is a sub-tab on the page itself.
Saved views replace menu items
“Reorder now”, “Spend, no sales”, “Past due” are filters worth naming. They sit in the same list as the screens because that is how the work is actually described.
The honest cost
Someone who does not know a screen’s name has to open the palette and search. Worth pairing with a one-page cheat sheet for new employees, or a first-run tour of the five rails.
