Some things I would use if possible:
Finding dupes by tag/extra/custom column data.
Finding dupes by size, but fuzzy, specifying byte difference.
Custom grid styles, particularly by a tag/extra/custom column.
Different grid styles able to be saved in folder view settings, instead only of one global.
New tab when on a branch view or search, duplicates that tab and its view. Right now mine seems to only open the root path of the branch/search.
If any of these are already possible, my apologies for overlooking.
