Hello Jakub! sorry for my late response.
We have some larger features we're working on, but the list is not public. Is there anything specific you'd like to see in future?
I'm not sure if that has something to do with the extension. But i noticed for example when i'm in a function, and i want too view the implementation or references of a method, it always says that no implementation or references could be found. Same for type definitions, and definitions.
But i'm not sure if this is an issue from VSCode, or the PHP devsense extension..
