We have received feedback that  our family of "yellow circle" icons sometimes makes it difficult to  discern the different ones.

To that end, we are working on new versions of the entire product family, although at this moment, I am not sure how many we will be able to get into Notes 8.5.

However, the good news is that we have been able to change the 3 icons for the 3 Symphony editors (Spreadsheet, Presentation Tool, and Word Processor), as shown in the picture below.
