"This year there are a few big additions, one of those being Wolfram Alpha backed data types (which is what you saw in that M365 briefing). That functionality will be rolling out to Insiders in the next month or so."
Brian Jones (OFFICE): this is exciting news, thanks!
One more small, but important matter: Poor visibility of the highlighted cell is an issue some with less-than ideal eyesight have been submitting feedback/suggestions on for years. The highlighted cell border is the same color and just a tiny bit thicker than all the other cells. Obviously one can move their gaze back and forth to the Name Box and Formula Bar to double-check, but this greatly increases fatigue when doing spot editing on large spreadsheets. Couldn't an option be added change the highlighted cell's border color, adjust its thickness and/or change background color to something that stands out more?
