Hello everyone,
This does not work for me.
I'm on the 24.6.0 release of TB. When I click on the yellow button "Run filter on folders" > nothing happens. No menu appears, no bar or any form to filter my folders.
There's there something I did not understand?
Can you help me?
Sorry for my english, I'm French.
