I just upgraded from 2.2 to 2.5. My memory may be playing tricks on me but I thought I was able to enter characters in table 12 and get instant filtering.
if I type a*, all a* apear, and conitinuing ab* the filter would change.
If it wasn't this way before I must have been imagining. Now I have to exit the table 12 focus to get the directory to update. If it wasn't that way before I suggest that for an improvement.
