Change the color of inactive virtual columns in the editor

[Gustavo_Eduardo]

Working on my application, I find it useful to use virtual columns in cases where a calculation needs to be done multiple times within the same app. This allows me to create a virtual column and then, where the calculation is needed, point directly to the virtual column, thus avoiding doing the same thing multiple times; simply optimization.

Now then, at a certain point in development, there remain (by error or omission) some previously created virtual columns that are not being used. It is necessary to eliminate them since they serve no function other than just being there. For example, sometimes I create a filter in a virtual column, then call that filter in several actions, and of course, later I delete the action and the virtual column may remain without me noticing.

AppSheet natively marks virtual columns with a blue color. It would be interesting if user-created virtual columns that are not being used could be marked with another color—I imagine yellow, but that's just to give an idea of how it might look in the editor.

Each user will judge whether that virtual column will be used in the future and therefore leave it there, or if that virtual column is no longer needed and should be deleted.
