Pro feature: clear "find related" filter when clicking [Next Unread mail] or [leave thread] button

[RealRaven2000]

While using the new "find related mail" feature I found that it can be improved by removing some kyboard steps after dealing with a search. Here is my workflow example:

• after going to the next unread mail (an order notification) I click on find related to find mails with the same name in subject line
• I then have to select the most recent previous mail (this would be a nice step to automate but not to be discussed here)
• I then flag the email as renewed (at the moment by using the appropriate flag label in the mail header toolbar, provided by the tag toolbar Add-on
• Then I need to clear the search and go to the next unread mail. Currently I use the keyboard combo [ESC] followed by [N]

I would like to replace the last option by simply clicking the "Next unread mail" button in the Navigation bar (current folder bar), or also (ideally) by pushing [N]. This removes the effort of having to type [ESC] as well (which sometimes may also unintendedly hide the search field).

The current behavior is that [N]ext unread mail operates on the filtered result set and will usually result in Thunderbird jumping to the next folder with unread mail, which is disruptive. I want to simply keep doing my operations, do the next unread mail and search for related mails. Ideally Thunderbird would have this as an optional behavior but I think this isn't possible at the current point in time.

Here is a preview version:

QuickFolders-mx-6.7.1pre15.zip

It works to reset the quick filters search box when the "move to next unread mail" button is clicked here, after the "find related mail" search has been used. (search box must contain the string that was filled by find related)

The behavior can be enabled by setting the switch
extensions.quickfolders.findRelated.behavior.goNextResetsSearch = true

this can currently be done via a right click on the find Related button:

note that this will reset the search also if you keep search sticky and the old search term was brought to a different folder. It will still reset the search when you click "next unread".

To try the version above download zip file and drag the file into Thunderbird Add-ons Manager (do not extract contents, it won't install like that)

I found that I also need the reset when the "unread" toggle beside the go next button in Navigation bar is not active. Therefore I decided to always reset the quick filter (search text) when pressing next mail there. This way I can remove a filter when looking at old orders and sending follow up mails to a particular customer. After sending the email I want to go to the next mail in chronological order, without having to press ESC or clicking the reset search icon:

QuickFolders-mx-6.7.1pre20.zip

Again to enable the behvior, set extensions.quickfolders.findRelated.behavior.goNextResetsSearch = true

Also to note: the reset only works if you leave the search filter as it was set by the last "find related" operation, reset won't work if you edit the search string manually. This is by design!
