What "filter assistant"?

[MarjaE2]

I can't find a full manual, just the short explanation here:

https://addons.thunderbird.net/en-US/thunderbird/addon/quickfilters/

"Activate the filter assistant. ..."

What "filter assistant"? There's a "Quick Filter" icon in the toolbar, but it just shows or hides the "Unread," "Starred," etc. options.

P.S. Thunderbird had not recognized the filter. Solved that.

"Activate the filter assistant. ..."

What "filter assistant"? There's a "Quick Filter" icon in the toolbar, but it just shows or hides the "Unread," "Starred," etc. options.

It is activated when you click the button that is automatically added to your toolbar:

Once clicked, it turns red: ...and shows this message at the bottom:

then you start moving mails to "teach" quickFilters what to do. It can create filters accordingly using the filter assistant:

it will extract different information (current tags / folder location / maybe whether it is starred / subject / who has sent it etc.) and turn these into Conditions & Actions for the filter. When I created the Add-on this was mainly to save time from having to select the folder location as that was always very painful (I have 100s of folders).

If you have already moved the mail earlier you can also generate a filter from it, via right-clicking the message and selecting "quickFilters: create filter from message"
