Is there a visual indicator for cells with conditional formatting?

I’ll be quick about this; I have no idea whether a cell has an applied conditional formatting or not without having to dig into the Format > Conditional Formatting… dialog box. For me, this is unintuitive and a little annoying if I’m trying to set up more-than-simple cases of conditional formatting for columns of data.

Is there any other way, requiring less clicks, that I can find out if a cell is conditionally formatted? The ideal implementation in my mind is something like the edit state of the document on the status bar (asterisk if edited from last save, check/blank otherwise) combined with the visual cue of comments in cells (a little corner arrow).

None of which I’m personally aware. I’m a programmer type so when I needed to do a few thousand of these recently, I made a template, picked apart the ODS file, and created a new one programmatically. However, this is clearly neither ideal nor approachable for most, and I would have preferred exactly what you’re suggesting.

My suggestion: spend a few minutes looking through the various enhancement requests and “crazy ideas” and if you don’t see it, submit this idea.
