Feature Request

Is your feature request related to a problem? Please describe

I've setup litterally hundreds of branches in Cacti and there as of right now two issues, every time I change a branch, I have to clear something onf the filter for things to show up, and also right now, the "filter" is not updated in the URI whenever I change the filter itself. So the feature request has two parts:

1. If you are on a branch, have a filter and templates set, when you hit save, make that save just for that branch
2. When you add search criteria to the Tree search, make sure the filter goes into the URL.
