It would be nice to have the ability to apply a color code to items in the receipts and payments list, inter account transfer list, journal entries, etc. Something that is simply user supplied value. It would make it easier to visual “things you want to remember to address at a later time”.
Add a custom field which does not appear on printed documents.
Thanks, good enough.
You can even change the color-coding of custom field content. I wrote about how to do this quite a while ago, in the context of workflow status. But I think you will get the idea: Changing colour of text in drop down menu - #2 by Tut.
