- Help dialog (?, F1, Datei > Hilfe): user topics, all shortcuts and the formula functions with one search over everything. Topics and shortcuts are plain data in data/help.ts; the function list comes from codeReference.ts so new built-ins appear by themselves. - While a formula is edited, the grid outlines each referenced cell/range in the colour of its position in the text, and the outline can be dragged to move or resize the reference, as in Excel. Point-mode picks (click, drag, arrow keys) are outlined too, so keyboard picking is no longer blind. - Underline as a cell format, plus Mod+Shift+B/I/U toggles that switch on unless every selected cell already has the format. - A formula committed with open parentheses or an open text literal gets the missing closers appended; anything that still doesn't parse is left alone so the usual error shows instead of a guess. - Cells and tables with a fill but no text colour get dark or light text by WCAG contrast instead of the theme colour (no black on black).
