I like that it does give a wider view of my mail what I absolutely can not deal with is what this add-on does to my searches.

When I have this add-on enabled and use the address bar for a search this add-on adds %2525252525252B between each word in the search.

For instance if I type the following question in the address bar:
What are the 3 elements of a contract?
This is what I get:
What%252525252525252Bare%2525252525225Bthe%25252252252525B3%252525252252525Belements%252525252525Bof%2525252525252525Ba%2525252525Bcontract%252525252525B?

And of course that search leads no-where because it is not reading the 8 words that I originally typed it is reading one long word with a bunch of %252525252525B adding in.

I have no idea why it does that but it is VERY ANNOYING so I have disabled this add-on and will never use it again.
