The mess I have got myself into before I realized I was duplicating filters

Quickfilters allow duplicate attributes to be added to existing filters.

When using Thurderbird with an IMAP account often filters fail to work.  

This means you can sometimes accidentally add filters again thinking a filter
does not already exist.. 

If you add the filter again to an existing filter with quickfilters, quick
filters allows you, resulting in duplicate attributes in the existing filter.

Also a nice to have would be a tool to find and remove any duplicate attributes
that already exist

There are some new troubleshooting modules that will be added in the next
version of quickFilters; non-working filter conditions can happen when
conditions are merged between "any conditions" and "all conditions" - I found
quite a few of these in my own filters. When merging I actually remove
duplicate conditions.

There was also a bug with importing subject conditions which can be fixed with
the troubleshooting tool of version 4.3.

>Also a nice to have would be a tool to find and remove any duplicate attributes

judging by the screenshot you are already using it :)

it's just hard to fix automatically, filters can have many different conditions
so it is sometimes hard to tell which one is the duplicate. 

Question: when you create new filters, do you use the assistant method (move
email to folder manually with assistant enabled)? - because then you would see
already existing filters that move mail to that folder.
