It's easier for me to manage IQ if it's not full of fields and grids I don't use and I've been going through and deleting many of them.  Obviously some are protected and cannot be deleted.  I assume anything that can be deleted is safe to delete?  By safe I mean I'm not going to find out somewhere down the line that anything is broke in any serious way or doesn't work with an upgrade because of fields I've deleted?

 

What concerned me is I deleted a field named InfoQube that I thought I had created at one point.  But now I see a grid names "search" for which that is the source.

 

Thanks
