Try it: drag a bar to move it (linked tasks cascade, the finish updates in the tiles), drag its right edge to change the duration, drag the little circle at the end of a bar onto another bar to link them, double-click a cell to type (name, duration, start, finish, predecessors like 12FS+2d), double-click a row or bar for the full record, right-click to recolor. Drag the divider to resize the grid. Every tile drills down. Switch schedules with the chips; the What-if draft can overlay its parent.
