I realize this topic hasn't been touched for a few years, and if something better than the LVOOP Assistant exists, I'd be happy to hear about it. The GOOP suite is nice, but handles member VI icons poorly, I just wanted something to change the color theme, which is how I found this.
Anyway, I don't know if this is a problem introduced with newer versions of LabVIEW since this was last updated, but any change I make to member VI icons through the theme editor or the library icon viewer does not force a save of the VIs of a class. The functionality works, but I can close the entire class, reopen it, and see the old VI icons. It doesn't prompt me to save them when closing and doesn't show an asterisk in the title bar of any VIs.
I haven't found a way to save all the VIs in a class after changing icons outside of opening each one individually and saving it. Doing a save all or right clicking on the class and choosing save all (this class) don't work.
Did this work previously? Is there any chance of it being looked into at this point?
