I would LOVE it if I was able to edit gdb (aspatial) tables using the Attribute Editor option in the Editor toolbar.
It doesn't happen often, but there are certain projects where I need to maintain aspatial data, and as it stands this is an awkward thing to do, as I need to edit each record / attribute individually in the attribute table view.
The ability to edit using Attribute Editor would mean that I could quickly and consistently apply the same attribute to a number of records, and the transposed view would mean that I could easily visually validate the updated records.
