On both the whitelist and blacklist screens, it would be immensely beneficial to add a “date/time” added column to each entry.
I know I do this all the time when surfing. A a whitelist here and there to see if it works or not. If it doesn’t fix what I want I go back in and remove the entry.
By adding a date/time column that can be sorted, it makes it VERY easy to quickly back out of changes to remove recent additions.
Much easier then having to remember what you added and scroll through a list of possibly hundreds of entries to find it.
If not possible perhaps a new option of “last 25 entries added” for each to make removing them easy to find.
