Show HN: Vertical sheet tabs for Excel (multi-row too)

I've created an Excel add-in that enables multi-row and vertical sheet-tabs in Excel: FormulaDesk Navigator Filter by color as well as custom tags. Why? Because Excel files with many sheets are a pain to work, endless scrolling to get to sheets... Current state: the public beta testing period is about to end. Is it useful to you? (I know, a bit late in the game to ask that, but please let me know if you have any suggestions or advice) Try it here: https://www.formuladesk.com/formuladesk-navigator/ Thanks, Gareth Hayter.
