Application Shell 40 block design & features
ApplicationShell40 is a spreadsheet application shell built with Shadcn UI. The title row has a spreadsheet icon, the file name, a star toggle, a saved status, a collaborator, a Share button and the user avatar. The menu bar holds File, Edit, View, Insert, Format, Data and Help dropdowns.
A rounded toolbar has undo, redo, print, zoom, currency, percent and decimal buttons, bold, italic and strikethrough toggles, fill, borders, alignment, wrapping, comments and functions. A formula bar shows the selected cell name.
The grid has sticky column letters and row numbers, and clicking a cell selects it and highlights its row and column. Sheet tabs, an all-sheets menu, an add sheet button and a sum readout sit at the bottom.
