Analyst Workbench Demo — full-screen grid + widgets
A full-screen working surface: one master grid over the whole dataset, and a movable widget workbench underneath that reacts to what you select. Filter and sort in the grid header, tick row checkboxes, then drag and resize the workbench panels into the arrangement you want — like laying out charts over a sheet.
The sheet
The master grid is deliberately tall — it is the primary working surface. Header filters, sorting, clipboard copy, and checkbox selection all work client-side; the selection feeds the workbench below.
The workbench
Everything below rebuilds from your selection (no selection = the whole book). Drag a panel by its edge to rearrange; pull a corner to resize — the layout is yours.
The workbench panels are draggable and resizable (GridStack). The arrangement currently resets when the selection changes — persistent layouted sheets are the next feature on the roadmap.
