Remember Filter tool?
One of the new tools in 2017 version is Modeless Filter tool. We upgraded functionality of a basic Filter tool and made it Modeless. Meaning that tool allows you to select instances via a dialog box which is always open during the modeling, editing, etc. You can also place it on second screen. Choose instances either by the current view or whole model, then shows instances in a tree sorted by different properties (e.g. category, phase, room).
