Question / #4534

I have a question related to ListBlockCol_TaskSumEfforts.

You mentioned at implement some sort of caching for efforts and number of subtasks that you have no idea how to deal with folders which shows a filtered list of e.g. subtasks (= not all tasks; some tasks are e.g. hidden to the user) and their summed up efforts.

My question is if you already found a solution for this problem?
I would like to know this in relation to add list of all (not only open) tasks for person because I implemented the page where only the tasks of the selected person are shown and there is the same problem with the folder and the summed up efforts (at the tree view).
