Suggestion for prefilters

[herve06]

Hello

As seen on this thread http://fabrikar.com/forums/index.php?threads/suggestion-for-prefilters.37888/#post-190554

I really would like also to filter with "not null" or "not contains" option.
Is there any news about this ?

There is also 2 "default" filters : this month (april 2014), and last month (march 2014).
It would be appreciated to have also : last 30 days (from 15 of march until now)
