@sebastien We cheat.....we use the built-in pendant, anything that we want to be highly visible to the user we use a leading capital for the variable name so that it appears near the top of the variables list.  We have the ability also to use popups and concatenate what is displayed, meaning we can make easy to use custom messages that contain strings and variable data.  We can either use the standard popup where you get the stop program/continue buttons or if its purely a notification we will popup a message that only has an ok button (cannot block execution though), we also have written the ability to close those whenever we want programmatically so that if we need to display something else we can as popups come to the bottom of the stack so you have to close the previous popup to see the new one.  This has allowed us for the time being to not need to develop any other displays for use in our cells.
