I complete agree that this would be a great feature. As a matter of fact the only reason I decided to come here to the boards was to submit a similar feature request, that the custom views would be saved to the user for the project, not to the entire project so it affects everyone.
Because it’s so good to be able to customize the default filtering for each user.
But the idea from Tim_Jasper for saving multiple filtering with url’s is even better, and to support filtering based on simple URL variables.
I really hope something like this will be added in the near future
