The filter icon has been moved, thats ok. 
Using the filterfunction as it is now, gives very hesitant response.! say 1-5 seconds before it reacts.
Clicking ‘Content’ I can see the project has some 2100 events and 1900 characters
I run MacOS 15.6.1 on a Mac Studio with 32 GB Ram and ample disk spaces, so I gather that the coding here “might be overwhelmed by all the new options”.
Hoping for (huge) improvements, in due time. It is afterall day 1-2 after release
