Hi Anna - Trust me, this is feedback we have given to the Product team since the beginning. ;)
The good news is that sometime in the future (no committed date yet), they will change the sorting so that the 0 projects will be at the bottom of a user when you expand. That way you don't have to scroll through all the time to make sure you are seeing everything.
In the meantime, we have applied filters but wildcards haven't worked for us (i.e. $$TODAY+2w) so the team does have to update the filter every week.
If using the 4 week view starting with this week, the Resource Manager will have the filter set up in Resource Planner where Task >>> Planned Start Date is Less Than or Equal to May 9th at 5pm and the Task >> Planned Completion Date is Greater or Equal to April 12th at 9am
This filter has helped them out a lot. Hope it helps you too. :)
