Faster opens Workbooks open much more quickly. Sheets4U reads Excel files in memory and shows saved results right away (similar to LibreOffice), then recalculates sheets as you use them — so multi-sheet grade books and large .xlsx files feel snappy. More accurate formulas Grade letters, weighted totals, and other Excel-style formulas recalculate more reliably. Fixes cases where letter grades could show “F” even when the total was above the failing threshold. LARGE, SMALL, blank cells in math, and many common functions now behave closer to Excel and Numbers. Easier to read and edit • Column letters (A, B, C…) stay pinned while you scroll down • Right-click cells to Wrap Text or Unwrap Text • Long text can display in full across empty neighboring cells (LibreOffice-style overflow) Productivity • Sort Ascending / Sort Descending reorders only your current selection • New RND button next to Functions: choose a numeric range and decimal places (0–9), then fill the selection with random values

• Sort Ascending and Sort Descending operate on the current selection only. Selected rows are reordered and values stay in the selected range (they are no longer written down the whole column). Multi-column selections are sorted by the active column while keeping each row’s cells together. • New RND control next to Functions: set a range (for example -80 to 50) and decimal places (0–9). OK fills every selected cell with a random value; Cancel closes without changes.
