That sounds like a plan, thanks!
If I may, there is one more question, which is very important: What about the tasks which are created within a project. Currently everybody can see every task, even whent he project within which the task is created has limited visibility to Project Members, only. Is there a way, to achieve the following: When a task is linked to a project, which has limited visiblity to Project Members, than this task should also have limited visibility onyl to PMs? (I did not find a way in the manuals/help of Phabricator about that.)
I did find that when I create a task, I cen limitits visibitlity (see image below) but that of course should not be done by the user (he would see all other projects/spaces) and thats very bad, too).
