Context: Thunderbird 26 beta, Windows 7
One of the nice things about Thunderbird (and for me, one of the most intensely irritating) is the ability to create filters by right-clicking the sender's email address and selecting Create Filter From...
The irritation comes from this: where is the filter stored? It does not appear in the list of filters when selected from the menu via Tools>Message Filters...
, so I have no idea whether it has actually been created or not. And I can't manage what I can't see.
This issue, by the way, has been with me for years and is not just with v26beta.
